LETTER FROM THE CHAIR OF THE EDITORIAL COMMITTEE
Energy flows from high to low back to high again. The push in Colorado between September and mid-November can be draining, invigorating, and challenging. It seems as if the first hint of cool weather sends the contractors into a tizzy of needs, and we all work with vigor until the asphalt plants shut down and we have a pause and regain our bearings. Spring cleaning always happens for me in the Fall, except I call it tying up loose ends. I hope you all get a moment to tie up your loose ends too.
This edition contains the second installment of “Where is Colorado?” by Earl Henderson. The “tapering” between accepted monuments makes me wonder how l would reconcile a survey along the south line of Colorado. Look at the map attached to the Colorado Monument record system and check out the meandering line and lack of monuments shown in Baca and County along the “fractional townships” running along the southerly boundary of Colorado. I can’t wait for installment 3!
The following members placed in the NSPS Map Contest. Letters went out last week:
• Stephen Bloomfield - Second Place Misc Category
• Shelly Stone - Third Place ALTA/NSPS Category
• Julia Keilman - Second Place Boundary/Cadastral Category.
The recent passing of Gaby Neunzert and Warren Andrews will be addressed when we honor them in our February edition. Please send in articles, stories and memories to share with our community of surveyors.
• We also lost Joe Zylstra, age 82, who, while not a member, was known to many in the surveying community as the owner of Zylstra Baker Surveying Inc.
• Many of us received notice that Kenneth Goff, owner of Underground Consulting Services (UCS) and a sustaining member of PLSC, passed away suddenly on October 10th. Ken will be remembered by me for making sure my projects were completed on time even if he had to do the field work himself.
• Brandon Martinez passed away on August 24, at the age of 33 while climbing with friends at Williams Peak, just outside Aspen Colorado.

I am writing to express concerns regarding the challenges encountered in pursuing licensure in land surveying through the Colorado Department of Regulatory Agencies (DORA). The process, which is already demanding in its technical and educational requirements, is further complicated by several operational inefficiencies that significantly delay the licensure timeline for applicants.
CHAPTER NEWS
One of the most notable difficulties is the extended response time from the agency. Throughout the application process, both myself and other applicants have experienced substantial delays in receiving feedback or clarification on submitted materials. This lack of timely communication makes it difficult to address any discrepancies or issues with the application, further extending the process.
Additionally, the absence of live representatives to communicate with has created a significant barrier. Often, applicants are required to navigate the system without direct guidance, relying solely on online resources or email responses that are often delayed. The ability to speak with someone directly would not only expedite the resolution of any concerns but would also provide much-needed clarification on the application requirements, which can be vague or open to interpretation.
A specific issue that has led to confusion and delays is the requirement for an associate degree in land surveying. While educational requirements are mentioned, it is not explicitly clear in the initial documentation that an associate degree in land surveying is mandatory. This lack of clarity results in
many applicants unknowingly submitting incomplete applications, only to be informed months later that additional qualifications are needed. This ambiguity, combined with the slow response times, causes the application process to take several years for many candidates.
In summary, the process of obtaining licensure in land surveying through the Colorado Department is hindered by delayed communication, an inability to speak with live representatives, and unclear educational requirements. These obstacles unnecessarily prolong the time it takes for qualified individuals to enter the profession, ultimately affecting both their careers and the industry as a whole. I urge the Department to address these issues to make the licensure process more efficient and transparent.

Southwest chapter
The Southwest chapter of the PLSC convened for their regularly scheduled meeting on September 17th. While the chapter continues to actively search for future guest speakers, discussions during this session primarily revolved around forming committees to oversee the planning and execution of upcoming chapter events. The goal is to increase member participation and generate fresh ideas for potential speakers.
The chapter received a brief update from the La Plata County Surveyor, who shared insights into local issues and projects. The conversation highlighted the valuable collaboration between the chapter and local surveying professionals. Attendees discussed updates from GIS sites, monument reports, and the involvement of the county surveying office.
The chapter is committed to strengthening ties with the local surveying community and leveraging their expertise to enhance the value and relevance of the chapter’s activities for its members. By forming dedicated event committees and maintaining open dialogues with local stakeholders, the Southwest chapter aims to foster greater engagement and generate innovative ideas to benefit the professional development of its members.
The Southwest chapter of the organization will convene for their next regularly scheduled meeting on December 17, 2024.

WCLS would like to express our sincere gratitude to Dennis Mouland for his insightful presentation on ethics and completion and extension surveys at our Fall Seminar. The event was attended by 37 individuals, including four CMU Tech students. It was heartening to see a mix of our regular members, those who are unable to attend chapter meetings consistently, and aspiring land surveyors.
We extend our thanks to our host, the Grand Vista Hotel, as well as our vendors, Frontier Precision and Vectors, Inc. Additionally, we appreciate the invaluable assistance of David Holmes, Vice President, and Kurt Shepherd, Board Member, in making the seminar a success.
The Chapter is enthusiastic about inviting Mr. Mouland to return for next year’s seminar. We are also exploring the possibility of a larger venue and implementing online registration to enhance accessibility.
Our September chapter meeting was held at Grand Junction City Hall. Representatives from CMU Tech, Mesa County, the City of Grand Junction, and CDOT provided updates. Attendees engaged in robust discussions on topics such as the WCLS scholarship award process, Chapter financial procedures, the growing use of remote sensing, and the new continuing education requirements. Additionally, we made progress in planning a holiday party in January, with more details to follow.
The Chapter expresses our heartfelt condolences to the friends and family of Brandon Martinez, a promising young surveyor, who tragically passed. Also, Tom Sylvester recently lost his home and garage to a house fire. The Chapter encourages members to help support the friends and family of Brandon and Tom during these difficult times.
The next chapter meeting will be held on November 13 in Grand Junction.

Where is Colorado? Episode 2-Southeast Corner
by Earl Henderson Earl@ZenithLS.com www.ZenithLS.com
If you remember from Episode 1, the movement to create the State of Jefferson, later to become Colorado, didn’t start until 1859. So, it won’t surprise you to find out that the first survey related to the boundaries of Colorado, completed under the command of Lt. Col. Joseph E. Johnston in 1857, had nothing to do with Colorado. The purpose of the Johnston survey was to determine and monument the south line of the Kansas Territory, 37° North Latitude, from the west boundary of the State of Missouri to 103° West from the Greenwich meridian, being the east line of the New Mexico territory. Astute readers will remember that the east and west boundaries of Colorado are defined by 25° and 32° West from the Washington, DC meridian, not the Greenwich meridian. In fact, the Greenwich meridian wasn’t adopted as the prime meridian by the US until the International Meridian Conference in Washington, DC in 1884. So clearly, 27 years prior to that conference, the definers of New Mexico were being prescient. (See photo 1.) Refer to image VI-B-2 (1855) to see that the south line of the Kansas territory was intended to terminate at the east line of the New Mexico territory at that time.
The surveyor working under Lt. Col. Johnston was J.E. Weyss. When they reached what they thought was 103° West, they took astronomical measurements, set a large
sandstone monument marked “103 WL,” (see photos 2 and 3, next page), and went back to DC. In DC they were able to compare the astronomical measurements made in the field with measurements made based on Greenwich time and found out that they overshot the mark by a mere 4.36 miles. Now let’s give them a break. First, it was 1857. Nor did they have any way of measuring precise time out there in hostile Indian territory. Lt. Col. Johnston, along with four companies of the First Cavalry and two companies of the Sixth Infantry, were supposed to be protecting them, but even so, several members were killed.
As a result of the discovery in DC of the Johnston/ Weyss monument being in error relative to 103° West, Capt. J.N. Macomb was sent back out west to set a monument in the correct location of 37° North and 103° West. My resources appear to indicate that Macomb was instructed to set his monument 11,582’ east of the Johnston/Weyss monument on their surveyed line, which Macomb did. However, it turns out that this is not the correct distance from the Johnston/Weyss monument to 103° West. Later surveys determined that the Macomb monument is still 2.5 miles west of 103° West.
In 1868, Ehud N. Darling, US Surveyor and Astronomer, surveyed the south line of Colorado, marking the line
Photo 1
I have not found any reference to why the Greenwich meridian was used at this time to define New Mexico. If anyone has such a reference, please share it. As it turns out, New Mexico is unusual in that the east boundary is defined from the Greenwich meridian and the west boundary is defined from the Washington, DC meridian.

between Colorado and New Mexico. This line will be the subject of Episode 3, but it’s worth mentioning here for several reasons, historical continuity being one and that it’s important to understand that Darling started his survey at the Macomb monument, which was presumed at that time to be at 103° West.
In 1874 John J. Major was contracted to run the line along 37° North from the corner common to Colorado, Kansas and the Indian Territories (now the pan handle of Oklahoma) west to the Johnston Monument. This is the first instance where the SE corner of Colorado was monumented at 25° West from DC. And it was done without much fanfare. His notes read, “Ran west from the corner of Kansas, Colorado and Indian Territory…”. In 1908, Arthur A. Kidder and Jay P. Hester (we’ll hear from them in later episodes) found a sandstone monument at this location and replaced it with a 3” iron post monument. In excavating the old monument, they found a champagne bottle (I have no documentation of what they were celebrating). But apparently there is no monument at this location currently. There is no monument record for this location. Presumably the construction of the road that currently passes through the location having caused the monument to be destroyed.
Major’s survey proceeded west along the 37th parallel as he determined it, at 10 chains south of and about parallel to the Johnston/Weyss line for 37° North. Just past his 42nd mile he encountered a monument marked by Darling as the corner of Colorado, New Mexico and the Indian Territories at 103° West. Apparently, Darling, who was supposed to start at the Macomb monument for 103° West, started at a monument he found on the Johnston/Weyss line which he mistook for the Macomb monument. This monument is about
13 miles east of the Macomb monument. To Darling’s credit though, after surveying those 13 miles, he found Macomb’s monument and started over. Major; however, had a decision to make. Under the impression that Darling had started his survey 13 miles too far east, Major decided to taper the difference between his determination of 37° North and the Darling/Johnston/ Weyss line for 37° North starting at his 35th mile marker to the first Darling monument at about 42? miles west of the SE corner of Colorado. He then continued along the Darling/Johnston/Weyss line to the Johnston/ Weyss monument. Upon reaching the Johnston/Weyss monument, Major altered the monument adding “1874 NM Major” to it.
The final determination of 103° West of Greenwich was completed in 1881 under Richard O. Chaney and William W. Smith, US Surveyors and Astronomers. The North-South line they ran has become known as the Cimarron Meridian and defines the east line of New Mexico along the west line of Oklahoma. At that time they were able to use astronomical observations but also telegraphic exchange signals for measuring time differences to more precisely locate 103° West Longitude from Greenwich. They also established a monument at the north end of their line at what they believed to be 37° North Latitude.
The final determination for the NE corner of New Mexico was made by Levi S. Preston in 1900. Preston retraced Major’s line east from the Macomb monument and intersected that with the Chaney-Smith line for 103° West (the Cimarron Meridian), setting his monument at the intersection of those lines, which is about 14 chains south of the Chaney-Smith monument for 37° North (see photos 3 and 4, next page).
you visualize some of what I’ve described.
You may think that this ends the saga of the south line of Colorado between Kansas and New Mexico, but it doesn’t. As far as I can tell, the south line of Colorado runs along the Major line from the SE corner of Colorado for about 35 miles to where Major started his taper toward the Macomb monument. Between that location and the Preston monument, the maps I’ve reviewed appear to show a taper from Major’s ±35 mile location to the north, then returning to a due westerly direction until about 1 mile east of the Preston monument, where the
line tapers again to the Preston monument(the north line of Section 7 in Oklahoma on the resurvey plat). I don’t know how this came to be. But I’m very curious about it. So, if anyone has any documentation about this particular area, please feel free to contact me and share it. I will update you if/when I get that information.
Next time we’ll attempt to understand the south line of Colorado from the Macomb monument west to the Four Corners.
Stay safe out there.

Trailblazer: John Von Nieda, City of Fort Collins
Interview by Celine Bromley, Larimer County Surveyor
I had the pleasure of working with John Von Nieda for five years at the City of Fort Collins. As I mentioned in my previous Trailblazer interview with Ron Perkins, all the surveyors I have worked for are very tall; the tallest one being John! He put his height and athleticism to good use playing professional basketball in Australia after college. John was born and raised in southeastern Pennsylvania. He and his wife ended a year-long travel in Switzerland, her home country. Eventually they moved back to the States and had two kids, Evelyn and Tristan. John’s greatest pleasure is to watch his kids thrive and make their own happiness. John loves to travel, hike, bike and garden. I have been the recipient of many gardening tips from John as this is a hobby we both partake in. One of my most memorable things about John is how he frequently gave us pop-quizzes in spelling and made bets for milkshakes! John not only has a wealth of knowledge in surveying in and out of the United States borders, but you will never have a dull conversation and will probably learn a little something extra about life.
How did you get into surveying? By accident. I worked in Douglas Wyoming for the US Forest Service Engineering Department out of college. Ninety percent of what they did was surveying. We camped for a week at a time and got paid extra for it, like per diem. I surveyed for 2 years in Australia and 5 years in Switzerland as well.
What do you love about surveying?
The field work; the hidden treasure aspect of it.
Who was your biggest professional influence and why?
So many! My first boss in Australia, Michael Loy; he made me want to be a surveyor. He was very enthusiastic, positive and took the time to teach. Other strong influencers are Doyle Abrahamson, Wally Muscott, Steve Lund, and Frank Drexel among others. I would see their plats and really wanted to emulate that kind of work.
What are your biggest challenges with this profession?
Hiring qualified people.
What is the most significant issue affecting surveying as a profession?
The lack of qualified people and younger surveyors.
What is the biggest change in surveying that you had to adapt to?
GPS and scanners for surveys, deciding when and where to use them.
What career accomplishment makes you most proud?
Over the 30 years of supervising, 15 of my employees have achieved licensure (and three of those were civil engineers!)
Outside of your career, what has been your biggest accomplishment?
Seeing how resilient and independent my kids are.
What was your favorite project and why?
An Engineers without Borders project in the Peruvian Amazon. The project began as a topo for a water delivery system for an indigenous village in 2007. It took a total of about 40 days over the span of four years. The topo morphed into a boundary survey for their territory through virgin rain forest; approximately 6km by 15km in size. Tons of challenges, the toughest of which had little to do with surveying as you can imagine. We worked closely with the Ministry of Agriculture who certified the survey in the end, and who curtailed encroachments by petroleum and timber companies among others. Deeply satisfying work really.
If you could start your career again, is there anything you would do differently?
Yes, I would have started with Surveying.
Do you have any advice for other up-and-coming surveyors?
Find a mentor, ask a lot of questions, find surveys you think are done exceptionally well and learn from them.
What survey books would you recommend?
Brown’s of course, and Jeff Lucas’s ‘The Pincushion Effect’.
Is there any knowledge that you would like passed down?
YES!!!

Adventures in the Sandbox –The Northern Colorado Virtual Sandbox
Laine Landau on behalf of the Northern Chapter
First, I would like to thank the Central Chapter, and in particular, Brian Dennis for the plans for the Virtual Sandbox. Second, I beg his forgiveness for not following them.
The Northern Colorado Chapter partnered with the Poudre School District’s “Futures Lab” to build a virtual sandbox for use in Northern Colorado. The student team was the “consultant”, and the PLSC Northern Chapter was the “client”. We kicked them off with our requirements, provision of the Central Chapter’s plans, photos, a budget, and all the website directions to build the sandbox.
The “Futures Lab”, now known as the PSD Career Tech Center, is a Poudre School District program designed for high school students to explore careers, develop in-demand skills, earn industry-recognized credentials, and college credit. Pathways include Audio Production, Computer Science, Construction & HVAC, to Natural Resources. The students were excited about making the sandbox accessible to multiple age and ability groups and designed two sets of legs to change the height of the box to respect needs for a lower table to fully engage in the learning experience.
The other client request was for a more portable sandbox that the district and the chapter can share more easily. The design they came up with has sturdy removeable legs which allow the sandbox to be transported in a small SUV, rather than a pickup truck.
We had some hiccups along the way: None of the PSD computer science staff knew Linux or was comfortable following the directions to get Linux set up as the operating system on the computer. The initial production and programming schedule was not met for the client specified deadline of the 2023 Construction Con event. We borrowed the Central Chapter’s Sandbox which worked well at the 2023 Construction Con event and gave the “Futures Lab” students a good view of the working sandbox. Shout out to Heather Lassner for volunteering time for that event. Unfortunately, while the Central Chapter’s sandbox was parked at my office, our IT department recycled the PLSC computer since our company asset tag was still attached. Unbeknownst to them, the computer’s operating system had been switched from Windows to Linux and contained an upgraded video card. This was a big loss and slowed down the Northern Chapter’s sandbox as we prioritized getting the Central Chapter’s sandbox up and running. All components are now clearly labeled!
The student Project Manager for the “Futures Lab” was fantastic. If she decides to go into Construction management, she’ll be an amazing asset. The students did a great job but needed additional support. I’d like
to thank Patrick Hartley for taking an interest in the project. Without him there would be no machines with Linux, no X-box Kinect, no upgraded video cards, and no calibration expertise. He also took time to go up to the “Futures Lab” to get the new Sandbox running for a school event. He had to jump in and build a cage for the projector, and mount the X-box Kinect, as well as run the calibration he was originally called in to do. Last week Patrick ran down to Loveland to help Becky Roland and Todd Beers get the Central Chapter’s sandbox “live” for a High School Counselor’s conference at the Ranch.
We have our second sandbox event scheduled for early November which will be a STEM event for 6th grade Poudre School District girls. As we set up the sandbox, we are going to film the setup and calibration steps and will produce a video that will travel with the sandbox to make future setup easier. We also need a local champion and a PSD champion who understand the setup and can teach others to use and maintain it.
On October 23rd we debuted the Northern Colorado sandbox at the 2024 Construction Con event at the Ranch in Loveland. 700 students from all over Northern Colorado attended the hands-on event. Vladi Skrejev with Tait and Associates stepped up to assist and was an enthusiastic partner in making land surveying relevant to the high schoolers. This is the 3rd year for the event and PLSC has partnered with ACE Mentors to share a booth with the sandbox and engineering competitions like bridge building and tower construction. We are hoping the Poudre School District will house the sandbox.
Thank you to Brian Dennis for introducing many of us to the virtual sandbox and for the beautiful craftmanship and sturdy construction he invested in the Central Chapter’s sandbox. We are hoping Northern Colorado students benefit from the box we’ve built as have the numerous students, scouts, and counselors the Central Chapter’s has influenced. A special thank you to Becky Roland as one of the chief sandbox movers!

May
KENNETH GOFF
10, 1968 - October 12, 2024
Ken made his first appearance to the world stage on May 10, 1968 in Middletown, CT. He lived a full life of love and laughter. He passed on to God while in the comfort of his home on October 12, 2024, at the age of 56. Ken leaves behind his loving wife Kelly, and his cherished sons Sebastian and Alexander. His family was the core of his life, both blood and chosen.
Ken grew up in Vermont working summers as a ranch hand and later a volunteer firefighter. He joined the Army 152nd Engineers where he made lifelong friends and proudly served his country.
Ken married Kelly in 1993, and they had two sons who made his world complete. He sang with Certain Sounds chorale in Vermont. In 2002, he became self-employed helping start Underground Consulting Services (UCS), a new niche utility locating company in Colorado. Ken absolutely loved his work and learning more every day. He loved his employees, supporting them personally when needed. He loved meeting his clients and knowing more about them and details of their work.
He often visited Disneyland with child-like abandon and looked forward to annual camping with friends and family. He was a Patriots fan, but also cheered for the Broncos, and was proud when the military was recognized. Ken liked to engage in political talk and opinion; and compare religious
interests with historical facts and verbatim Bible quotes.
Ken joined Christmas Chorale in Denver and accepted an invitation to join the Passion Play of Denver, which he faithfully continued up to his passing. He brought a sense of family to all, and offered his love and personal support to anyone having a hard time in life. Throughout Ken’s life, he always included his friends and family. He checked in on people often, to make sure they are doing alright and know he still cares.
Ken is predeceased by his father, Kenneth H Goff, Sr, his mother, Patricia Goff (Harvey), his grandfather, Francis Harvey, Sr., Grandmother Sarah Harvey, many aunts and uncles, and friends. Ken is survived by his wife Kelly, sons Sebastian and Alexander, sisters Barbara Goff, Christine (Goff) Wood, Cousin David Raymond, many special cousins, extended family, and friends.
Ken always remembered each person in his life who passed. Each year he would honor the life and memories of every individual with a personal heartfelt toast; at the anniversary of their passing, or their birthday, a time of year that was special, or an event or memory that they shared. ,
BRANDON MARTINEZ
July 14, 1991 - August 24, 2024
Brandon passed away suddenly August 24, 2024, at the age of 33, climbing with friends at Williams Peak, just outside Aspen, Colorado.
Brandon was born July 14, 1991, to Barbara and Roger Martinez and was the youngest of their 3 children.
Brandon accomplished so much in his short life - always setting goals and accomplishing them. He was an Eagle Scout; he graduated 5th in his class from Fairfield High School where he ran track and cross country, was in
ROTC, Jazz Band and was the Drum Major for the Scarlet Brigade Marching Band his senior year. He graduated from UC Berkeley in 3 short years with a Bachelor's of Art in Geography.
Summers he enjoyed road trips and traveling the world with his friends. After a short internship at a local surveying company in Benicia, CA, working on projects like the Apple Campus in Cupertino, Brandon moved to Colorado to further his career. He finally settled in Grand Junction and bought his first home.
In 2023 he started his own surveying business. He had a passion for the outdoors, skiing, camping, motorcycling, hiking, completing the Colorado 14ers and his own Summerfest – he loved organizing all these activities with his friends.
He will be missed terribly by his parents, Barbara and Roger, his older sisters Desiree and Chelsea (Piotr) Orzechowski, his nephew Logan and nieces, Charlotte and Margot and many aunts, uncles and cousins, and so many friends.
He was preceded in death by his beloved grandparents Archie and Ursula Martinez and David and Roberta Lotz. We were all so very proud of Brandon.
A Celebration of Life will be held in Grand Junction, CO, October 26th and in Fairfield, CA, November 23rd.
