Located in Death Valley National Park's Wildrose Canyon the Wildrose Charcoal Kilns are considered to be the best surviving examples of such kilns in the western United States. The kilns were only used for a short time around 1878 to provide charcoal to power nearby smelters. There are 10 kilns at the site each standing 25 feet tall with a circumfrence of 30 feet. Each kiln was capable of converting 42 cords of pinyon pine logs into 2,000 bushels of charcoal in one weeks time.
