Wildfires have forced evacuations at two U.S. national parks in the West as summer monsoon storms increase lightning in the region.

Two fast-moving wildfires—the Dragon Bravo and White Sage fires—have scorched more than 45,000 acres, destroyed the iconic North Rim lodge and dozens of structures, and led to long-term closures in the Grand Canyon.

The North Rim was evacuated Thursday because of wildfire and will remain closed for the rest of the season, the park said in a statement.
