Secret Yosemite (movie)

Just finished watching this movie.

Very educational. One more thing I learned is that the drift of pesticides in air (from outside industrial agriculture) is destroying some of the most abundant animal life in Yosemite — yellow legged frogs.

Watching the rock climber (Lincoln?) scale El Capitan is stunning!
