Hell's Half Acre Wilderness Study Area

In Idaho, BLM manages over 66,000 acres of public lands in the Hell's Half Acre Wilderness Study Area. The 5200-year-old lava flow resembles flat moonscape with deep crevices and sparse vegetation. Pioneer plants, such as lichens and mosses, inhabit the barren lava surfaces. Mule deer, antelope, coyotes and rabbits are the most frequently sighted mammals here. Sage grouse and mourning doves can also be seen inhabiting the lava flows.
