Somewhere near the center of Nevada, on the western slope of the Toiyabe Range, there’s a little meadow beside a creek running down from the mountains. In 2019, long before I had ever been there, a man named James Fredette drove his mobile home down the gravel road from the highway and went fishing. It was a lucky day: He caught three big rainbow trout. Then, as the light turned golden and began to fade from the canyon while Fredette packed up his gear, he thought, why not, and walked back down to the creek to try his luck panning for gold. He turned up a few nuggets, right there. Yes, it was a very lucky day.
