CalFire has officially declared the Dome Fire in Yosemite National Park fully contained after the blaze burned 6,788 acres. Officials have begun reopening trails and sections of the park that were previously restricted due to fire activity.
Why it matters
The fire required a significant mobilization of more than 1,000 personnel to protect sensitive structures and prevent further environmental damage. The containment effort allows Yosemite to return to normal operations following weeks of disruption.
The Dome Fire burned a total of 6,788 acres within park boundaries. More than 1,000 personnel were involved in the operation to contain the fire, which necessitated the closure of Glacier Point Road for over two weeks.
