History
The first documented discovery of gold in the Rocky Mountain region occurred on 1850-06-22, when Lewis Ralston, a Georgia prospector headed for the California gold fields, dipped his sluice pan into this stream near its mouth at Clear Creek. Ralston found about 1/4 ounce (6 g) of gold worth about five dollars. Ralston's companions named the stream Ralston's Creek in his honor, but they all left the next morning, drawn by the lure of the California gold fields.
In the spring of 1858, William Green Russell and his brothers searched the creek for gold. Later in the year, Lewis Ralston brought another group of prospectors back to the site of his first discovery.
In 2010 officials discovered that the defunct Schwartzwalder uranium mine was contaminating groundwater near the reservoir, threatening the Denver water supply with concentrations of uranium some 1000 times the human health standard. The proposed cleanup involves rerouting Ralston Creek.

“Let it suffice that in the light of these two facts, namely, that the mind is One, and that nature is its correlative, history is to be read and written.”
