The CAL Fire Tuolumne-Calaveras Unit reports that a new base camp is being established to support up to 1,000 firefighters on Sims Road off Highway 49 near Chinese Camp to alleviate the extensive travel time between the Incident Command Post in Merced and the northern edge of the Detwiler Fire.

Officials notes that the establishment of the camp is not an indicator of any fire threat to Tuolumne County. CAL Fire officials remind travelers in the area to use caution.
