Halstead Fire, Idaho • Earth.com

Last update: October 19th, 2019 at 2:00 pm

Sparked by lightning, the Halstead Fire had burned 18,522 acres (7496 hectares) of the Salmon-Challis National Forest by August 3, 2012. The fire is burning in a mixed conifer forest, much of which is dead lodgepole pine. The trees were killed by an insect infestation, likely mountain pine beetles.
