A large Utah wildfire kept emergency responders from safely reaching the remote site of a helicopter crash on Saturday as other fires burned across several Western states, including one that closed part of Mount Rainier National Park. The Friday morning crash of a Sikorsky Skycrane helicopter in Utah’s Fishlake National Forest ignited a new fire that spread to connect with the existing blaze that has now scorched nearly 174 square miles (nearly 451 square kilometers). “The site is now inside the fire perimeter itself,” the fire incident management team said Saturday afternoon. The National Transportation Safety Board will investigate the helicopter crash once their team can examine the wreckage. Officials urged the public not to speculate or spread rumors about the cause at this early stage.
