My quest in Yellowstone today--a search for the boreal chorus and columbia spotted frogs. I ventured out to Lamar Valley and wandered around dozens of wetlands and ponds. Those little guys remained elusive--at least by sight--as I listened to the distinctive call of the chorus frog at several ponds.

Despite the lack of frog sightings, my travels in the park were not in vain as my photo diary below demonstrates. I encountered five grizzly bears, observed bighorn and bison mingling, watched a red-winged blackbird bathing, and an osprey fly over the Lamar River. I also spent a delightful hour watching the most adorable bison calves play together--you can view the video below, but beware as you may overdose on cuteness!
