This week, we hiked to the site where my field partner and I will spend our next three 10-day trips. This basin is very different from the last, and about 400 feet lower, with more trees and fewer frogs. Having been hit by the amphibian chytrid fungus, the mountain yellow-legged frog populations here are persisting at a very low level. Frogs are even being flown up to higher fishless lakes in the basin to try to bolster their numbers, and this basin harbors one of those lakes.
