Halleluia! My mind can rest easy now! It'll be the first time in 29 years!
K-Wise has nailed it, I think. These pictures were taken at the top of Big Cottonwood Canyon just east of Salt Lake City. Not too likely to run across a wombat, unfortunately, but the geograpy is just right for a Pika. That picture you included there even captured his nonchalant and sort of dismissive attitued toward the larger mammals in his presence. He was kinda snooty.
Thanks everybody!
