Residents who fled their homes near the wildfire at Guernsey State Park in southwest Wyoming are being allowed to return to their homes. However, the park remains closed. Thanks to ideal weather conditions and a heavy dose of water dumped from helicopters, firefighters have gained 80% containment of the fire. It was 20% contained on Monday. The fire, which has burned about four square miles, started Saturday and forced the evacuation of hundreds of campers and park users. While one private vacation cabin was lost, firefighters were able to protect the park facilities.
