 A new lightning caused wildfire discovered earlier this week on the southeast end of the Williams Ranger District will be allowed to burn naturally within a pre-determined management area to reduce fuel loads and promote healthier landscapes.

Due to the remote location and low to moderate fire behavior observed, the Thumb Flat fire is being allowed to move naturally for the benefits of reducing hazardous fuel accumulations, increasing protection of local private inholdings, and restoring forest health. The overall strategy will be to contain the fire within a road system and various control features surrounding an area of about 475 acres.
