“Anthropocene, the new epoch that the human power has become so large and active that it rivals some of the great forces of Nature in its impact on the functioning of the Earth system.” -Will Steffen
T
he dynamic geological alternation unintentionally created by the Anthropocene has developed a toxic beauty, which has continuously
imposed rhythms and effects on the living environment. It starts to raise human awareness of accidental nature, to discover an epochal beauty from geological decay. It presents an unseen state, an in-between position that allows a compatible, complementary co-existence of humans and nature.
O
wens Lake in California, 250 miles north of LA, is a perfect example of toxic beauty because it shows how two contrasting human forces:
destroy and mitigation co-exist in one place. Owens river today holds extraordinary beauty by the red salt river, shallow green pond, and dust. Yet, it is under environmental recovery where mitigation, irrigation, managed vegetation, and tillage zones are under construction. The confronted compromise and collaboration between nature and artificial nature would lead to a hybrid new reality.
S
imilarly, using the Spiral Jetty created by Robert Smithson, as an example, the site was chosen for its unusual ecological and geological
characteristics in the Great Salt Lake. The artwork in a continually changing state whose form always stays active and reflects the state of entropy. The artwork treats architecture as a ruin in reverse, an entropic experiment, where the natural ground acts as a toxic material agent to communicate with human intervention.
T
he project will combine images of toxic landscapes with samples of chemical decay. It is a synthesis of toxic nature with entropy and
how to construct geologic infrastructure through the beauty of toxicity. The materials use the images of the site as the growing palette to form a new “Material Nature.” By mixing the eroded landscape with industrial materials, the project tries to create a geo-aesthetic infrastructure for living beings and nature.

ATER SOURCES
California relies on three main, interconnected water sources: mountain snowpack, reservoirs, and aquifers: The Sierra Nevada snowpack, which melts in the spring and summer, provides runoff to rivers and reservoirs. In normal years, melted snowpack typically supplies about 30 percent of the state’s water supply. The state’s reservoirs store water from precipitation events and receive the runoff from melting snowpack. Less precipitation and snowpack results in decreased reservoir storage. When the supply of surface water is unable to meet demand, groundwater is pumped from aquifers, accounting for nearly 60 percent of the state’s water supply in a dry year. California has built a water delivery infrastructure that is likely the most extensive anywhere on earth, capable of moving a drop of water that originates near the northern border all the way down south to the Mexican border. Through the development of this infrastructure, man has rearranged California’s natural assets to meet societal needs, making the state unrecognizable from its presettlement history in the process (Water and Power Associates N.D.).

A Aqueduct
The Los Angeles Aqueduct is one of three water systems delivering imported water to Southern California. The Los Angeles Aqueduct system delivers its liquid load entirely by gravity. Fourteen hydropower plants along the aqueduct’s path take advantage of the elevation drops, generating 400 million kWh for the city in 2008. The system includes five storage reservoirs, 142 tunnels totaling 52 miles in length, 12 miles of inverted steel siphons, 24 miles of unlined conduit, 37 miles of open, cement-lined conduit, and 97 miles of covered conduit. First one was built by Mulholland which supplied from the Owens river, and the second one was now mainly supplied by the Haiwee Resevoir (Water and Power Associates N.D.).

OWENS LAKES
STOLEN THE WATER The Owens Valley region of California sits at the eastern base of the Sierra Nevada Range. The mountain create an extremely effective rain shadow, and the water that collects in the mountains eventually flows downward into the valleys on either side. Historically in the Owens Valley, this water would find its way into the Owens River, and then flow south to end its journey at Owens Lake (Los Angeles Depends on Imported Water N.D.).
After ranchers and small farms had entered the picture after the Paiute, Owens Lake was around 110 square miles in size, which was one of the largest natural lakes in California, and covered a piece of landscape that, if located in Los Angeles, would stretch from Santa Monica to Glendale, and north into the city of San Fernando. But this immense lake of salty water would soon begin a drastic change, and the fundamental nature of the landscape completely changed by the end of the 1920’s.
In 1913, the City of Los Angeles completed the Los Angeles Aqueduct, a channel that would take the water of the Eastern Sierra and Owens Valley and divert it over 200 miles to the south to slake the thirst of the budding metropolis that was Los Angeles. With this diversion in place, the majority of the natural flow of water into Owens Lake was halted, and the lake shrunk to just forty square miles and only a few feet deep.
As the lake disappeared, the salinity levels rose, creating a hyper-saline brine pool. Very small ponds of collected water that sit along the western edge of the historical lake shore are the very last existing remainders of the lake. These pools are still extremely saline, which supports the growth of a bacteria that colors the water a deep red; much of the water that is left today resembles the color of blood. With the water gone, the exposed bed of Owens Lake was at the mercy of Owens Valley winds, which can become impressively forceful due to the topography of the long, narrow valley. Wind has always been present in the Owens Valley because of this geographical fact; the accounts of early explorers make understandable note of the weather from time to time. With Owens Lake gone, the dust storms grew more and more severe throughout the 20th century. As Los Angeles continued to collect Owens Valley water by way of the LA Aqueduct (and later a second pipe used to collect more water further north, as well as a growing number of groundwater wells), the dried expanse of land at the southern end of the valley became a growing health concern for all of the communities near it (Mott 2017).
Owens Lake was the single largest source of particulate air pollution in the entire country by 2000s. The Los Angeles Department of Water and Power (who controls the LA Aqueduct) was required to begin work that would mitigate this pollution. Though the details of these original agreements, as well as ongoing ones related to further court orders and requirements, are very complicated, the overall goal is straight-forward: The Los Angeles Department of Water and Power, having originally diverted all of the water out of Owens Lake, is required to bring the pollution levels caused by its actions within the acceptable limits set by the state of California. Once this goal has been met, LADWP will have met its set of requirements according to the agreement.

MATERIAL RESEARCH -METAL ELECTROLYSIS
ELECTROLYSIS GROWTH Electrolysis is a technique that uses a direct electric current (DC) to drive an otherwise nonspontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential. 1.5 VOLTS
Based on the coral regeneration system in Panama, there are floating installations harnessing the tidal power from the constant movement of passing vessels into the canal. Instead of the shipping industry damaging coral and marine left, they are empowered to help sustain and develop the coral structure. Richard was trying to experiment with electrolysis. This process is the way to represent water displacement, control and water saving basins of the Panama Canal Locks. “ Through an almost scientific experiment level of accuracy, the amount of water within the central chamber can be controlled and changed. The number of flakes demonstrates the ability of the locks to save far more water then the proposed 60%. The system is then developed into a project 3 VOLTS
as dual use infrastructure- whereby the water is no longer used simply for transit and trade, but can be activated.The experiment demonstrates an additional prototype that is able to clean oxidised iron objects through the use of electrolysis. This process’s ability to function however is still dependent on the water levels. The electrolysis experiment and the submerged object revealed an intriguing and ethereal underwater and industrial environment, of exposed material and changing states.”
The experiment focuses on the form of biorock, a self-growth system. For the first part of the process is to try to form a structure around the mesh. He mixed materials such as oyster shell, portland cement and salt crystals and steel to produce texture and material of it. Especially for the 6 VOLTS
salts which can react with the metal meshes, would create variation in texture and composition, which could potentially as he mentioned “to form a larger architecture structure.”
The experiment started with testing metal meshing in a series of water containers for seperate test results. These containers were tested with different voltages and times in order to explore what voltage produces the most successful, plentiful and stable mineral accretion in a few days or weeks. The images show in the left is the tested result of copper reacted with the meshes , which produced similar materiality with my project.

MATERIAL RESEARCH -METAL ACCRETION
ANODE MATERIAL ACCRETION ”In cathodic protection, a metal anode that is more reactive to the corrosive environment of the system to be protected is electrically linked to the protected system, and particularly corrodes or dissolves, which protects the metal of the system, and partially corrodes or dissolves, which protects the metal of the system it is connected. As an example, an iron or steel ship’s hull may +12 HOURS
be protected by a zinc sacrificial anode, which will dissolve into the seawater and prevent the hull from being corroded. Sacrificial anodes are particularly needed for systems where a static charge is generated by the action of flowing liquids, such as pipelines and watercrafts, Sacrificial anodes are also generally used in tank-type water heaters (Richard 2016).”
For the second part of the experiment, Richard used the same parameters but opposite process to get accretion from the metal materials. Metal, Aluminium and copper were used as anode to test out.
+36 HOURS
The process of galvanic anode is particularly used in the shipping industry, which is used to protect buried or submerged metal structures from corrosion.
“They are made from a metal alloy with a more “active” anode voltage then the metal of the structure. The difference in potential between the two metals means that the galvanic anode corrodes, so that the anode material is consumed in preference to the structure. The loss( or the sacrifice) of the anode material gives rise to the alternative name of the anode. It is a chemical reaction occuring by the electrochemical mechanism (Richard 2016).” +72 HOURS
The clumps of mineral accretion under voltage variation would form solid and white aggregation like the “biorock” structure around the aluminum meshes. And the only byproduct of this process is hydrogen, which would also be used as the clean fuel of the future. It would be able to generate from the water and return to it when it is oxidised (Richard 2016).
