Scout Lake, Colorado, early October 2009. Apparently, this is the 5th largest beaver pond in Colorado. As I camped out here the night before, I was awakened every so often by a loud "thwack" of a beaver tail on the water. By morning, the temperature was just 5F and most of the pond had frozen. No more thwacking.
