Update at 3:04 p.m.: Yosemite National Park employees living in the Mariposa area and/or those who commute along Highway 140, due to increasing threats posed by the Detwiler Fire, are, with supervisory approval, being told that they may take administrative leave.

Update at 2:17 p.m.:  Mariposa Sheriff’s officials, who are now in a multi-agency meeting, are discussing issues relating to emergency management operations due to Detwiler Fire activity.

It is expected that since the town of Mariposa, currently under threat and being evacuated, that a community meeting scheduled for this evening at Mariposa High School will either be relocated or rescheduled. We will bring you that information when it becomes available.

Original story posted at 7:55am: The Detwiler Fire in Mariposa County, near Lake McClure, is up to 15,500 acres this morning and there is five percent containment.

That’s the latest information following the morning briefing at base camp. Challenges that faced firefighters yesterday included unfavorable weather, ample fuel and steep terrain. 300 structures are still considered threatened and an evacuation center remains open at the Mariposa Elementary School. Tonight, there is a community meeting planned for 6pm at the Mariposa County High School at 5074 Old Highway North. In Tuolumne and Calaveras counties, drift smoke will continue to be an issue today.

CAL Fire notes that the communities of Hunters Valley, Bear Valley, and Hornitos continue to be threatened as the fire encroaches on culturally and historically sensitive areas. Traffic along HWY 41 & 49 will be impacted as a result of road closures on HWY 49 near the fire.

The fire also continues to threaten power lines to the south of the incident, which supply power to Yosemite National Park.
