Jim Erdman led an informative nature walk November 1, 2008, from 9-11am. We met at his house for an introduction to Colorado forest history. Jim set up a demonstration in his driveway, cleverly using his truck as a prop: the side door was used to display a poster on Colorado’s oldest trees and the truck bed held a dissecting scope, tree-ring cores, and trunk cross sections. Next we then set off on a hike to look at several sites Jim had selected. See photos below. Thanks Jim!
