CHEYENNE, Wyo. (AP) — A wildfire in southeastern Wyoming has destroyed 29 homes and 31 other structures and threatens to remain active for weeks to come. The Mullen fire as of Wednesday has burned over 150 square miles of dense, beetle-killed pine in Medicine Bow National Forest. That’s up by about 20 square miles from Tuesday. The forecast calls for more dry and breezy weather and no rain or snow for at least several more days. Sheriff’s officials were unable to assess damage for days but say they have found cabins and other buildings burned in the Lower Keystone, Lake Creek and Foxborough developments.
