Carroll Davis was a passionate teacher of life sciences. He is the unsung Carroll who originated the first sections of the Indian Creek Trail. He was an accomplished mountaineer, working search and rescue and teaching mountaineering classes for decades. He was a bird-watcher, and couldn't take a hike without binoculars, bird book, and wildflower book. He volunteered for dozens of organizations, keeping careful notes in his neat handwriting. He loved to laugh and had a catalogue of jokes - clean ones - categorized in his scientific way. I used to kid him that his pick-up truck was covered with bumper stickers for "lost causes." An incredible man, Davis was. The earth lost one of its most ardent supporters. You changed my life for the better, Davis. Thanks you.
