The foothills of the northern Colorado Front Range offer hundreds of trails that wind through and over hills, meadows, mesas, forests and rock formations. Many trails are worthwhile year-round.
By studying a tree’s physiology, scientists are trying to determine how forests adapt to rising levels of atmospheric carbon dioxide and higher temperatures. By quantifying these effects, scientists hope to ascertain a forest’s ability to acclimate.
In Colorado’s San Isabel National Forest, along the eastern base of the majestic Sawatch Range on the west side of the Arkansas Valley, several trails skirt the edge of some of Colorado’s most accessible and scenic mountains.
