COSTILLA COUNTY, Colo. (CBS4) – Costilla County officials say they arrested a man for arson for the spring fire.
The spring fire has grown again and has lain on more than 38,000 acres.
Officials say hot temperatures, wind and dry conditions have fueled the fire on Friday. The crews worked on the east side of the fire near La Veta Pass to build a fire line with the help of air tanks and helicopters.
The area of Cuchara Valley was closed on Friday after the fire was evacuated over Highway 160, with no estimated time of reopening.

Firefighters say the southeast side of the fire will be difficult because of steep, rocky terrain and large amounts of dead wood.

The sheriff's office says they hope to learn more about lost structures over the next few days.
While temperatures are slightly cooler on Saturday, officials worry about strong, erratic wind speeds.  The fire burning to the east of Fort Garland is not included.
