About this map

High-altitude mining claims and remote alpine passes define this 2011 survey of the Colorado backcountry. The southern portion of the map focuses on the mineral heritage along the East Fork San Juan River, where the Black Diamond Mine, Robert Burns Claim, and Lady Bug Mine mark the historical footprint of prospectors. This rugged network of drainages includes Elwood Creek and Bear Creek, which flow through a landscape punctuated by named landmarks like Crater Lake and Long Trek Mountain.

Transportation through this difficult terrain is recorded by several strategic crossings, including Elwood Pass, Summit Pass, and Bonito Pass. In the northern reaches, the map detail shows the isolated McCormick Cabin and the open expanses of Big Park and Fivemile Park. This document captures the modern state of these traditional trails and sites, maintaining the nomenclature of the original mining era while illustrating the natural hydrology of Park Creek and its many forks.
