Keaton Baker left Iowa to work on trail maintenance in Yosemite National Park. “On the weekends, though you’re still in the wild, you can do pretty much whatever you find pleasing.” On one of those weekends, Keaton was having some fun rock hopping. When he stepped out of the river and onto the shore, a rattlesnake was sitting in the shade, likely asleep. Disturbed by Keaton’s sudden appearance, the rattlesnake bit Keaton on the foot.
