Update: Detwiler Flames Jump Containment Lines To Hike Acreage

Sponsored by:

Update at 7:15 p.m.:  CAL Fire reports a flare up on the Detwiler Fire Thursday afternoon sparked a 100-acre spot fire between outside the black containment line of the fire and Lake McClure at the end of Hunters Valley Road.

Ground and air resources were able to extinguish it in about two hours. That added up to a total acreage climb of 200 for Thursday, bringing the current official estimate to 81,550 acres. The containment held steady at 75 percent.

CAL Fire shares that crews continue to reinforce and build containment lines around the fire, including the spot fire area. Steep and rugged terrain continues to make access difficult in some areas. The number of personnel has decreased to 3,700. Resources are also down to 277 engines, 94 crews, 12 helicopters, 35 dozers and 52 water tenders. The number of threatened structures has dropped to 30. There have been 63 homes destroyed, 67 outbuildings and one commercial building.

The American Red Cross has announced it will close the evacuation shelter at the Mariposa Elementary School on Friday, July 28 at 10:30 a..m. (Please see below for additional fire details and lifted evacuations and road openings.)

Update at 4 p.m.: Drones are creating problems for aircraft battling the Detwiler Fire. The Mariposa County Sheriff’s Office says there have been multiple reports of drones flying in and around the fire footprint. Sheriff’s officials are asking that operators to remember that air support cannot fly when drones are in the skies and to keep the drones out of the fire area.  (Please see below for additional fire details, including lifted evacuations and road openings.)

Update at 2:45pm: CAL Fire officials are surmising at this point that an incident near the Detwiler Fire that created a flare up and jumped the black containment line this afternoon is a spot fire, possibly caused by the high temperatures and wind patterns.

Currently it is being reported as 100 acres in size and “sufficient” resources, according to CAL Fire, are aggressively attacking it. The location is described as between outside the black containment line of the fire and Lake McClure somewhere at the end of Hunters Valley Road. As part of the process, investigators will be checking to determine for certain if the incident is indeed a spot fire or another incident.
