Computer Terrain Mapping, Inc. 2005 map The Alpine Loop Recreational Resources data set shows the distribution of recreational resources on lands along the Loop. This data set is used to determine the Conservation Resource Value. Recreational activities in the area are numerous and include sight- seeing, hiking, biking, off highway motorized use, mountaineering, rock climbing, ice climbing, skiing, snowshoeing, snowmobiling, camping, horseback riding, fishing, rafting and kayaking. Recreation and tourism are the major contributors to the region's economy. Recreational elements included in the GIS analysis were roads, trails, campgrounds, huts, trail heads, ski areas (Silverton Mountain and Kendall Mountain), historic railroads and other historic sites. The Alpine Loop Spatial Analysis and Mapping Project inventoried natural and cultural resources and identified important areas where overlapping resources occur. The results from this project will provide an opportunity for area stakeholders - landowners, outdoor enthusiasts, surrounding communities, federal government agencies and local and national preservation groups - to come together to find solutions that maintain the Alpine Loop experience for future visitors and residents, while working within the framework of landowner objectives as well as local and federal government goals. The Alpine Loop Spatial Analysis and Mapping Project analyzed the Alpine Loop landscape, considering important natural and cultural resources along with the likelihood of development based upon building constraints. The Project aims to provide a planning tool for area stakeholders as they consider the variety of land management options and the future of this magnificent region. The next logical step will be to craft solutions that work within the framework of landowner desires, local and federal government land management goals, and available financial and technical resources to manage the area in a way that preserves the Alpine Loop experience for future generations. While the Alpine Loop lies within three counties - San Juan, Hinsdale and Ouray - the analytical work extended into a portion of San Miguel County. The resulting mapping and analyses will: 1. Create a spatial foundation to aid future projects in the Alpine Loop corridor; 2. Serve as a prioritization tool for evaluating the conservation potential of individual private parcels; 3. Provide the necessary framework for pursuing future funding opportunities. 2003 2005 See Standards for Digital Line Graphs (DLG-3) Complete None Planned -107.8725478 -107.2256611 38.08819806 37.73515861 None Conservation Resources Recreation None United States North America Colorado San Juan Mountains Ouray County San Juan County Hinsdale County San Miguel County Ouray Silverton Lake City None None.
