The only publicly accessible report for the Aspen Fire indicates the fire has bulled its way into the Kaiser Wilderness. The fire blew past newly established dozer lines strung along ridges in advance of the flames.
Firefighters are trying to keep the fire from moving into the 23,000 acre Kaiser Wilderness. Elevation and topography make the Aspen Fire especially difficult to battle. Elevation at Mammoth Pools is approximately 3,500 ft.. Kaiser Peak stands over 10,000 ft.
