    I sit on a secluded bench to take in the mid July views of Colorado State University’s Mountain Campus at Pingree Park, a remote site dedicated to field courses, conference retreats, and mountain research. As the evening sun bathes the valley in its warm, golden light, a gentle breeze carries calls of Ruby-crowned Kinglets, Wilson’s Snipe, and Mountain Chickadees to where I sit.
