Eight months after the Grizzly Creek wildfire burned nearly 33,000 acres in Glenwood Canyon, the surprising thing isn’t how much timber was blackened along the popular Grizzly Creek hiking trail near where the fire started. The surprise is how much wasn’t. On Thursday, a week after the U.S. Forest Service reopened the Grizzly Creek trail, there were pockets of burned trees, toppled timber, lines of fine ash where fallen trees went up in flames and other signs of the conflagration that swept some 8 miles along Glenwood Canyon on both sides of Interstate 70.
