Our final day in the field will be spent at Mount Evans, the highest altitude that can be reached by paved road in North America. Mountain Goats, Bighorn Sheep and Elk also spend their summer days at these higher elevations, and smaller mammals such as Yellow-bellied Marmot and American Pika may come out to bask in the sun. Butterflying is always interesting in the alpine tundra where a number of species are biennial. We'll look especially for Phoebus Parnassian, Mead's and Scudder's Sulphurs, Hoary Comma, Colorado Alpine, Chryxus and Melissa Arctics and Draco Skipper. Night in Denver.
Price includes all lunches.
