LAVA WILDERNESS STUDY AREA
The WSA is located on a flat plain and is an older lava flow including pressure ridges and pahoehoe lava (Pahoehoe is the Hawaiian word for "ropey coils"). The Big Wood River channel lies along portions of the WSA western boundary. Most of the river's flow is diverted for irrigation use before it reaches the WSA boundary. Here you will see lichens of different colors on lava and wildlife like deer, coyotes and sage grouse.
In Idaho, BLM manages nearly 24,000 acres of public lands in the Lava Wilderness Study Area. Hiking, camping and nature study can be enjoyed here. The rugged terrain and harsh conditions enhance the challenge of hiking and camping.
Visitors should be prepared for access via unmaintained two-track roads and remote backcountry hiking.
