Independence Pass (Colorado) - Independence Pass Foundation

Independence Pass Foundation

Since the days of the stage road avalanches and rockfalls often forced closures of the highway, partly due to the massive disturbance of the land during the road's construction. No attempt was made to remedy this until shortly after the automobile road was built. In the 1930s, as a relief project during the Great Depression, a crew from the Civilian Conservation Corps replanted the slopes around Independence, by then abandoned for two decades.

At that time, Aspen was a faded mining town whose population had dwindled to fewer than a thousand. Later in the decade the first efforts to develop a ski resort began. They continued after World War II, and in the later decades of the 20th century the city began to grow again. Other than paving the road, CDOT was unable to undertake any significant improvements to the highway corridor due to its projects elsewhere in the state and the requirement to coordinate efforts with the Forest Service, which owns most of the damaged land.

Beginning in 1976, Bob Lewis, an environmental activist in Aspen, organized revegetation efforts on some sections of the pass near the road that were having serious erosion problems. He realized eventually that a dedicated nonprofit organization would be a better way to address the many issues that remained. The Independence Pass Foundation (IPF) was established in 1989. Its first project, coordinated with the Forest Service, CDOT and Pitkin County, was the reconstruction of a curve near the popular Weller Lake trailhead.

The success of the Weller Curve project cleared the way for work on the Top Cut, the 1.5-mile (2.4 km) stretch just below the summit on the western side, which includes the most seriously eroded slopes anywhere in the pass corridor. Lewis had always intended to focus the IPF's efforts on it, and the organization began the first of several ongoing projects there in 1996. Work included the construction of stone retaining walls as well as revegetation. By the 2010s the results were evident.

With the success of these projects, IPF has been doing revegetation projects along the road below the Top Cut since 2004. Compost blankets were applied to large sections of the soil to replace lost nutrients. In 2009 the foundation began removing metal and rebar snow fences embedded in the soil just below the pass summit during the 1960s as part of an abortive project to increase meltwater capture by the Twin Lakes Tunnel. They were an aesthetic blight as well as an environmental problem, and had to be removed using a team of mules and helicopters due to the wilderness area restrictions. The last fence material was removed in 2012.

IPF has undertaken other projects to promote awareness of the work that needs to be done at the pass to protect its distinctive environment. Groups from local schools have spent a day up in the pass working and learning. Many have adopted the same sites and work on them with a new class each year. Along with the Aspen Center for Environmental Studies, the foundation also cosponsors a "My Independence" all-day walking tour of the pass for adults that covers ecological topics in depth.

Every May since 1994, just before CDOT reopens the pass, the foundation holds its popular Ride for the Pass, a charity bicycle race that serves as a major outreach event and fundraiser. It follows a 9.5-mile (15.3 km) route from the gate east of Aspen to the Independence townsite, climbing 2,500 feet (760 m) in the process. The IPF has canceled it twice due to poor weather.
