THE GRAND CANYON:
ENVIRONMENTAL ICON OF THE EARTH SYSTEM --
AND FOR US AS A PART OF IT
Let's stand at Mather Point on the Grand Canyon's South Rim, looking out over the world's most famous layout of this Earth’s geological epochs--
Not too far off to the west, once even visible from nearby Maricopa Point, are the remains of a uranium mine, a 1500’ hole dug down through and behind the Canyon's walls to reach the mine's toxic treasure. These Anthropocenic evidences may rust and erode, but traces will remain to tease geologists in the far future with the power and glory of Homo sapiens, a species that wrote its passage into the stone for the ages, as we altered the Earth System, Gaia some call it, to burn its forests and melt the ice sheets remaining after the last glaciation's end, the event 12 millennia ago that set us off to populate, explore, tame, and exploit that System beyond its capability to support us.
Fortunately for those of us who consider ourselves advocates for, lovers & protectors of, the Grand Canyon, 50 years ago the United States, after a grand public debate, chose to abandon a grandiose Anthropocenic dream, a scheme that would have produced the most long-lasting and visible industrial artifact of them all -- the electrification of the Grand Canyon founded on two large concrete hydroelectric dams with all their accompanying powerplants & high-tension lines, highways, residential & commercial urban support sites, mass recreation facilities, etc., etc.
