B.R. Moon 1987 Journal 19 14 April Bonanza King Mine and Canyon, Providence Mountains, San Bernardino county, CA. We couldn't find flat spots big enough for us so we headed back down to make camp at the canyon mouth. Didn't put in any pitfall traps today, but left them in the canyon to put in later. On the canyon bottom above the mouth some distance, I found a large rosy boa stretched across the rocky wash bottom at 1755 PST. The canyon wash shady, but still warm before dark. This snake was in the canyon just below the lowest piñon pines in the area (species account: Rosy Boa). We set up a camp at the top of the old ghost town south of the mine. I went to sleep just after the orange full moon rose above the horizon and became white and round in the night sky.
