Crews continue to secure the fire line along the north and southwest sides of the incident. The fire activity in the Jack Ass Creek drainage continues to be a point of concern for suppression personnel. Suppression efforts in this area of the fire will continue through the evening. The approaching weather front is projected to affect fire behavior and be a driver for suppression tactics.

August 23, 2020 at 1:52 PM

Crews continue to safely and aggressively pursue suppression efforts in the Jackass Creek Drainage East of Highway 49. Fire behavior during the previous operational period was not allowing any increase to containment, hampering air operations, and posing a significant threat to Priest Coulterville Road.
