ENVIRONMENTAL RESEARCH GROUP PRESS | Exploring Aspen's Grit, Passion, and Beauty







Environmental Research Group (ERG) Press is a small, non-profit, grassroots organization dedicated to publishing books, photographs, and maps about the Colorado mountains near Aspen.


ERG was founded by Bob Lewis in Aspen in 1976. Lewis was a 10th Mountain trooper during WWII, a hiker, skier, and a student of nature. But first and foremost, Bob Lewis was a teacher of conservation. He derived this ethic from biologist Aldo Leopold, who said that if you teach people to understand nature, they will grow to love it, and if they love it, they will protect it. As founder of the Environmental Research Group (ERG) and later the Independence Pass Foundation (IPF), Bob took those words to heart.


Bob felt there were no bounds to the lessons of nature, and so he conceived the means of sharing nature with the blind through his concept for the Braille Trail. “Louis Braille was blind, and when he was a child, his brothers and sisters took him out into the woods and he felt with his hands all the different forms of nature. He could tell apart the plants by the feel of their leaves, and he touched and felt all the animals on the farm, and knew they were his friends.”


On the last day of his life, while visiting the Rocky Mountain Biological Laboratory, near Crested Butte, Bob napped in a sunny montane meadow in the familiar and comforting arms of Mother Nature. For this dedicated teacher, the comfort of nature was always a salve. It nurtured him until the end. Bob Lewis died in the summer of 2005. He was 84.
