Ralston Fire

The Ralston Fire, burning in steep terrain and brush 10 miles east for Foresthill, California, is typical of late summer fires in the Sierra Nevada mountain range.

They burn a few acres, often less than 50 to 100 acres, on the date of origin. Once the fire reaches the extremely dry brush and the humidity drops, the fire explodes.

The Ralston Fire, burning in the canyon wall in Tahoe National Forest along the Middle Fork American River, has burned 3,712 acres as the morning report on InciWeb.org.
