Stony Mountain

Stony Mountain is a small community located 11km North of Winnipeg. Limestone and aggregates extracted from the quarries near Stony Mountain have been transported and used for construction projects in Winnipeg for almost 100 years. Aggregates are non renewable and the world’s most mined materials that are fundamental to the creation of a city. Aggregates give strength to composite materials such as concrete and asphalt that are used extensively to construct infrastructure and networks such as buildings, sidewalks, bridges etc. Aggregate is also used as base material under foundations, roads, and railroads for drainage applications and to stabilize urban building structures. Aggregate is one of the driving forces for economic growth.
STRIP OVERBURDEN First, thin layers of topsoil and overburden are scraped off of limestone deposits to store on site.

DRILL LIMESTONE Second, holes 3 meters apart from each other are drilled to create a grid-like form.
BLAST LIMESTONE ROCK Third, explosives are placed in the drill holes to blast the limestone. There are 4 different types of explosives that are used; slurries, dry mixes, emulsions and hybrid heavy ANFO. The type of explosive used is determinate on temperature, pressure, and diameter of the drilled hole. 8

Forth, different crushers give the desired size of limestone and aggregate for their uses.

CONSTRUCTION Last, lime and aggregate MATERIALS are used in mixtures for composite materials.
Limestone is heated in a kiln to create quicklime [calcium oxide]. Once quicklime reacts with water it becomes hydrated lime [calcium hydroxide].
lime Limestone is ground to a fine powder to create Portland cement. Limestone aggregate as well as Portland cement is found in concrete mixtures, which is used for buildings, bridges, sidewalks, urban highways, driveways, etc.
concrete
Lime is used in steel manufacturing and nonferrous processes. Some construction materials include galvanizing on steels [zinc], electrical component, household fixtures, stainless steel [nickel], oxides in glass and ceramics [lead], and casting metals.
metals
Limestone from 3/8� to 1/2� is used in asphalt mixtures. Asphalt can be found in construction materials such as rural highways, parking lots, driveways, pathways, etc.

STONY MOUNTAIN QUARRY
During site analysis, polar opposition was evident in spaces communicating: then versus now, openness versus enclosed, luminous versus dark, and natural versus controlled. These contrasts were the driving force for the design.

materiality
Upon arriving the site at dusk, a white form in the distance at the far side of the quarry, caught our attention. This luminous form lead us across the entire site. After jumping over water puddles, stubbing our toes on uneven terrain, and climbing up onto the cliff edge we found, to our disappointment, an old box cover for a truck. Nothing to our interest at all, however the contrasting material and shape in the site stood out in its surroundings, creating a point of interest, a destination. This is what introduced a lookout point to the design.

Polarispoint DESIGN INSPIRATION
Our inspiration originated from Instagram and the photos people were sharing on social media, but more specifically the type of photos they were sharing. The sunset images that were posted reflected our time in the quarry and refined details in the design to acknowledge the time of day people enjoyed and shared on site. From this analysis of Instagram activity and the observed and explored desire lines on site, it was evident that visitors and residents of Stony Mountain made it their home. They claimed the site as their own backyard, and were proud of what this unique undetermined space had to offer. Polaris, also known as the North Star, is used as a navigational tool on journeys and adventures composing a connection to astronomy in the design. Astronomy deals with the position, size, motion, composition, energy, and evolution of celestial objects. The same elements are applied to the quarry design by drawing attention to the setting sun and how it reflects and responds to environmental factors in the site; such as sitting water. Polaris also reflects activities instilled in the site such as recreational power-sports and the use of ATVs on every open sub-level space available, introducing a sense of play to the quarry design as well as defining a name to this specific location.

DESIGN INTENTION
Polaris Point is a network of connections through memory, imagination, and anticipation that establishes community identity. This relates to history of the site, present time, and future portraits that the quarry holds through natural and controlled succession. The concept of memory, imagination, and anticipation derives from J.B. Jackson (written in ‘On Landscapes’ by Susan Herrington) and is revealed as a larger idea in the quarry landscape but also found at a one to one scale important to human beings. This landscape idea of walking past history to the future, describes important dimensions of change through time that hold meaning to personal experiences and ecological development.

BUBBLE CORRIDOR
The bubble corridor demarcates natural succession on the north side of the quarry and controlled succession on the south side. The asphalt is situated on limestone aggregate to enhance the contrast between color and materiality. Asphalt was chosen as a form of material because limestone and aggregates from the site can be used as ingredients in the mixture. Colourful circles are intended to be painted on the bubble corridor to introduce play. There will be a variation of sizes from small to large.
Asphalt Mounds Multipurpose, games, select activities. Maximum height reaching 30cm.
Depressions A measure for collecting rain water, which can create intensities of reflection. Maximum depth of 5cm.

PATHWAY
The corten-steel grated pathway links the Bubble Corridor to Polaris Point, through a cultivated grove of bur oaks, pine trees and existing wood cover. The structural form of the pathway gives the illusion of a floating trail amoung the trees. It is elevated 30cm above the ground as to allow storm water drainage to move through the space and give vegetation the ability to grow in and around the sides of the path over time. The trail width varys from 2-3 meters.

POLARIS POINT
Polaris Point creates an enclosed space, balancing on the edge of the cliff. The lookout is made of angled slats that cast shadows from the setting sun. This allows light to filter into the enclosure also allowing one to peek through the sides of the lookout.

This quarry landscape has gone through different stages of life from biodiverse prairie lands to providing resources for industrialization and economic growth and now presently with this design, community development and ecological growth. This also falls in line with the landscape idea of the PAST and the memories it holds, the PRESENT explaining our industrialized age and the effects it has had on the landscape, and the FUTURE, the anticipation that humans and wildlife gain from successional transformations.

Limestone is heated in a kiln to create quicklime [calcium oxide], once quicklime reacts with water it becomes hydrated lime [calcium hydroxide]. Quicklime can be used to stabilize acidic soils as well as an additive in the refining process of construction materials. Hydrated lime is used in whitewash, mortar, and plaster.
Limestone is ground to a fine powder to create Portland cement. Limestone aggregates as well as Portland cement are found in concrete mixtures, which is used for buildings, bridges, sidewalks, urban highways, and driveways.
Lime is used in steel manufacturing and nonferrous processes. Construction materials include galvanizing on steels [zinc], electrical components, household fixtures, stainless steel [nickel], oxides in glass and ceramics [lead], and casting metals.
Limestone from 3/8” to 1/2” is used in asphalt mixtures. Asphalt can be used as construction materials in rural highways, parking lots, driveways, and pathways.
