The Grand Canyon National Park’s North Rim, often described as the park’s quieter, wilder side, is now closed indefinitely following a fast-moving wildfire that has engulfed more than 8,500 acres and destroyed dozens of structures, including one of the park’s most beloved landmarks, the historic Grand Canyon Lodge.

After the Dragon Bravo fire destroyed the historic lodge and other buildings on the night of the eleventh, Horning noticed on his phone app that two helicopters began water drops on the morning of the twelfth and slurry drops began on the thirteenth.

Nearly 400 firefighters are working around the clock on the Dragon Bravo Fire burning on the North Rim of Grand Canyon National Park, Tuesday.
