A fire burning on Fort Carson reached 800 acres on Tuesday.

Fort Carson Fire crews set controlled burns during the day to help contain the spread of the fire, a Fort Carson statement said. Those burns contributed to the total acreage burnt.

The fire is not threatening any structures and no injuries have been reported, the statement said.

The fire started shortly after 5:30 p.m. Monday and is burning in the base’s large impact area.

Soldiers train with large weapons, such as artillery, across large impact areas, and they are typically free of buildings and infrastructure.

The large impact area on base is east of Gates 10 and 12 along Colorado 115.

Crews are monitoring the blaze to make sure it stays within that area, the statement said.

Smoke is expected, the official said.
