The Aspen Fire burned from June 17, 2003, for about a month on Mount Lemmon, part of the Santa Catalina Mountains located in the Coronado National Forest north of Tucson, Arizona, and in the surrounding area.

It burned 84,750 acres (343.0 km2)[1] (132.4 sq mi) of land, and destroyed 340 homes and businesses of the town of Summerhaven.

In 2002, the year before the fire started, Congress had been requested to allocate about $2 million to cover the implementation of fire prevention measures in the Coronado National Forest.

However, that allocation was reduced to about $150,000 in the Congressional budget process.

There were originally suspicions that the fire was caused by a lightning strike,[2] but it was eventually determined to be human-caused.
