The Rim fire has spread rapidly across Yosemite, growing to become one of the largest in the National Park’s recorded history. The fire, which started 11 days ago, has destroyed more than 100 buildings and 184,000 acres of forest.

The fire is currently 20 percent contained, but has grown enough that it’s threatening stands of ancient sequoias and the Hetchy Hetchy reservoir which provides water to San Francisco. So far, Yosemite Valley had been spared.

This fire’s no joke. On Sunday, the fire burned through the Berkeley Tuolumne Family Camp Site and a popular run along the Tuolumne River was scorched. If you have plans to head to Yosemite for some outdoor adventure over Labor Day weekend, be sure to check whether the area you were planning to visit is open.

Here’s a map of the areas currently closed due to the fire:
