Grand Canyon National Park fire management officials began the Walla Valley Prescribed Burn on Saturday, June 21, at 6:21 p.m. They intended to burn over 6,000 acres in a set fire that “mimicked” a lightning fire. After a few test starts, they backed off that plan and determined not to set any more fires. Since then firefighters from the GCNP, Kaibab National Forest, Summit Fire District, Flagstaff Fire Department, Zion National Park, Carson National Forest, Holbrook, and Saguaro National Park have been attempting to contain the test starts.
No costs to date were reported.
The following was reported: Air resources making great progress. Active group torching with short range spotting. Planned Actions: continue to hold dozer line and utilize air resources.
