Walt Kaesler       Walt Kaesler is a retired architect living in Estes Park.  his interest in photography began more than thirty years ago and over the years he has accumulated files of slides, mostly of wildlife and wilderness landscapes.  The switch to digital photography, about four years ago, has been a major boost  to his photography.          Walt is a volunteer in Rocky Mountain National Park where he spends much of his time photographing the scenery and the four-legged inhabitants.  He is interested in using his photography to promote public awareness about the natural world, and inspire conservation of wild places, and the creatures that live in them.  Showing pictures of fabulous places, and beautiful wild animals is the first step in that effort.
