Mammoth WFM is based at the Inyo NF’s Crestview Fire Station, north of Mammoth Lakes, CA. Mammoth WFM started as a 10-person fuels crew in 2001. In 2003 the crew worked with Calaveras FUM to get a hang of fire use, and Mammoth FUM came into its current existence the following year, 2004. As the region has shied away from WFRB fires in the last few seasons, the crew has been used on remote, backcountry divisions on some of the major R5 fires: Reading, Mountain, Aspen, Rim.
