Aml Inventory And Characterization Upper Animas Watershed, Colorado Bureau Of Land Management

In 1993, the Bureau of Land Management (BLM) implemented a nationwide program to<br>inventory abandoned mine lands (AML) on public lands managed by the Bureau. The<br>inventory is expected to be complete by the end of 1997. The US Bureau of Mines<br>(USBM) provided extensive technical expertise and field crews for implementing<br>the AML inventory. In large part due to the USBM support, the AML inventory in<br>Colorado has progressed ahead of schedule, and is expected to be substantially<br>complete by the end of 1996. At the request of the Colorado Department of Public<br>Health and Environment (CDPHE), the upper Animas River watershed above Silverton,<br>Colorado was inventoried first as part of a group effort led by the Animas<br>Stakeholder Group. The upper Animas inventory was completed in 1994 followed by<br>detailed characterization of high priority AML sites initiated in 1995.
