Biochar Initiative Restores Hillside at Former Silver Mine in Colorado

Once an active silver mine in the early 19th century, Hope Mine recently transformed from a barren, abandoned plot into a verdant, restored landscape. Sierra Club Green Home explores the innovative biochar initiative led by the Aspen Center for Environmental Studies (ACES) that made it possible. Following the devaluation of silver and the Silver Panic of 1893, Hope Mine became a largely forgotten, desolate knoll. In 2003, the U.S. Forest Service (USFS) assumed ownership of the mine and began to assess the mine waste that had formed at the site in large piles of toxic rock. Although the Aspen Water Department found no evidence of danger at the time, the site’s proximity to Castle Creek raised concern: If a storm or other event propelled the slope-like layers of mine waste to erode, Aspen’s water supply could be contaminated.
