Introduction: Famous as a ski destination, Summit is the closest West Slope county to Denver. Like other small mountain counties, it can be hard to amass a long list here, but quality is often high. Summit's two large reservoirs are usually pretty dull, but once in a while they can come through with good waterbirds. In the winter Barrow's Goldeneye is reliable, and Rosy-Finches can sometimes be found at feeders in the ski towns, but otherwise this county is best as a warm-weather birding destination.
