About this file
This is an Inactive Mine Site Field Form document from the Colorado Division of Reclamation, Mining, and Safety, detailing assessment and closure specifications for five mine adit features within the Brasscap/Poughkeepsie project (Project #7684, OSM Project #561) located in San Juan County, Colorado. The project encompasses closures for five distinct mine sites: Rollo Lode (ID 01), Belcher (ID 02), Esquimaux (ID 03), Esquimaux lower adit (ID 04), and Gipsey Maid (ID 05), all accessed via Hurricane Pass north of Ouray in the HANDIES PEAK quadrangle. All five sites are owned by Houghton Land Preservation LLC, with one site co-owned by Helene Searcy Puls. The field assessments were conducted on September 6, 2012, by project manager CJL. Work scope includes installation of bat grates with access features (bat ladders and hatch access doors), concrete footers, and drain pipe systems at each adit. Alternative closure methods such as bulkheads with access and corrugated steel pipe options are specified for certain sites. Mine dump volumes range from 50 to 300 cubic yards across the five locations.
The document specifies preferred and alternative closure methodologies based on individual site conditions, accessibility constraints, and drainage characteristics. Sites with poor equipment access (ID 02, 03, 04, and 05) present increased implementation challenges compared to the Rollo Lode site, which has good equipment access. All five sites are classified as USFS/BLM recreation and wildlife areas with no identified bat habitat. Work specifications reference Standard Work Specification (SWS) 11 for grate installation standards and include provisions for removal of loose rock and talus at openings where necessary. The document provides detailed GPS coordinates, elevations ranging from 11,953 to 12,806 feet, and adit dimensions enabling precise project planning and execution.
