Two helicopter pilots who crashed while they were fighting a wildfire in Utah are dead, officials confirmed Saturday. The pilots were killed when their Sikorsky Skycrane helicopter went down Friday morning, according to the Sevier County Sheriff. The crash ignited a new fire that spread to connect with the existing blaze, which has now scorched nearly 174 square miles (nearly 451 square kilometers). Numerous fires also were burning in other parts of the West, including one that closed part of Mount Rainier National Park in Washington. Meanwhile in Oregon, hot and dry conditions helped an uncontrolled fire spread beyond 30 square miles (77.7 square kilometers).
