I spotted this small rattlesnake while clambering around on a jumble of large boulders that we had reached by hiking up out of the Nature Conservancy's Ramsey Canyon Preserve, a world-famous birding spot. I had been hoping to see the very rare Ridge-nosed Rattlesnake in this area, but was still quite happy to discover this more common species. I got within perhaps 30 feet to take this picture, but that's as close as it let me get. The noise I made taking a few photos from this distance were enough to disturb the snake into retreating to a crevice in the rocks.
