SUMMIT HUTS ASSOCIATION WEBER GULCH BACKCOUNTRY HUT PROJECT ENVIRONMENTAL ASSESSMENT SUMMIT COUNTY, COLORADO Proposed Action: Responsible Official: Further Information: Summit Huts Association Scott Fitzwilliams, Shelly Grail Braudis Forest Supervisor Winter Sports Lead White River National Forest (970) 262-3484 Location: Glenwood Springs, CO White River National Forest Summit County, CO Lead Agency: USDA Forest Service Dillon Ranger District White River National Forest Summit County, Colorado Abstract: The Summit Huts Association (SHA) is a 501-(c)(3) non-profit corporation based in Breckenridge, Colorado. It operates four backcountry huts under special use permit (SUP) from the Forest Service in Summit and Park counties. SHA emphasizes non-motorized, self-reliant backcountry travel and an intimate connection with the natural environment. This Environmental Assessment (EA) has been prepared to analyze a proposal designed to respond to current and anticipated consumer demands for public enjoyment and dispersed winter and backcountry recreation on the White River National Forest (WRNF) in Summit County. A final Decision Notice accompanies this EA. The draft Decision Notice and EA were previously subject to the pre-decisional objection process. In an attempt to clarify and resolve the objections, the Forest Service held meetings and conference calls with the objectors. The objection reviewing officer recommended changes that resulted in this EA and final Decision Notice. Approved projects may be implemented immediately. The purpose of the proposed project is for the construction of a new hut on National Forest System (NFS) lands administered by the Dillon Ranger District of the WRNF. The proposed Weber Gulch backcountry hut site is located at an approximate elevation of 11,500 feet on the northern aspect of Bald Mountain, east of Breckenridge. Bald Mountain is a popular year-round recreation destination for backcountry skiers, snowshoers, mountain bikers, and hikers. Weber Gulch provides backcountry skiing opportunities, especially in the northern-aspect trees. This EA discusses the Purpose and Need for the proposal, the process used to develop alternatives, potential direct, indirect, and cumulative impacts of implementing the No Action Alternative (Alternative 1) and the Proposed Action (Alternative 2), and Management Requirements.
