CASPER, Wyo. (AP) — Some people evacuated by a wildfire burning on Casper Mountain have been allowed to return home as firefighters make progress against the blaze.

Fire managers held a meeting with residents in Casper on Wednesday night. The Casper Star Tribune (bit.ly/PvR69k) reported that Natrona Emergency Management director Stewart Anderson told them that people who live on the east side of Hat 6 Road were being allowed to return to home starting Wednesday night.

The Sheep Herder Hill Fire has been less active because of cooler, more humid weather. It's holding steady at nearly 25 square miles and is 50 percent contained.

The cause of the fire remains under investigation.
