Heavy rains caused landslides on several roadways and trails leading to the top of the mountain.
The City of Phoenix closed the Central Avenue entrance to the park while crews cleaned up. The process ended up taking at least five months.
David Urbinato with the City of Phoenix Parks and Recreation Department said the damage was unlike what many rangers had witnessed in the past.
A landslide at the 2 mile mark covered the road with at least 6 feet of mud and several boulders.
Six people who were at the top of the mountain during the storm were trapped by the slide and had to be rescued by crews with Phoenix Fire Department.
Other entrances and facilities at the park are remained open during cleanup.
