A wildfire burning south of Salida is approaching 1,000 acres since it started Sept. 8.
Officials with the Decker Fire say the blaze is now 937 acres after growing by nearly 40 acres Saturday. There is no containment.
The fire is not threatening structures and there have been no evacuations, but the smoke has been severe at times. The Colorado Department of Public Health and Environment issued an air quality health advisory on Sept. 14 for northwestern Fremont County, southeastern Chaffee County and northeastern Saguache County. Officials say the fire may be visible from highways 50 and 285.
The fire is burning 9 miles south of Salida, with 293 acres burning in the San Isabel National Forest and the other 634 acres burning in the Rio Grande National Forest. It was started by lightning.
Officials say the fire is doing some good: parts of the Sangre de Cristo Wilderness have up to 80 percent tree mortality from beetle-kill and blowdown.
