This data set is used to determine the Conservation Resource Value. The historical resources map was derived from information from the Colorado Historical Society (CHS) supplemented with revision from BLM personnel. Purpose: 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.

Process_Step: Process_Description: CHS data were converted to GIS format. Sites were rasterized with buffers of varying size. 250m buffers were used for those sites that are on the National or State historic register. These sites were also assigned a high resource value (3). 100m buffers were used for those sites that were determined to be eligible for the National or State register. These sites were also assigned a medium resource value (2). All other sites were given a 50m buffer and assigned a low (1) resource value. This scheme was altered based upon input from BLM personnel.
