The city of Phoenix closed the hiking trails along Camelback Mountain until further notice after a hiker was trapped under a boulder on Saturday.
The Phoenix Fire Department rescued the out-of-town hiker, whose lower body became stuck under the 300-pound rock as he leaned against it to stabilize himself.
Firefighters were able to extricate the man and transport him to a trauma center with extensive injuries to his lower body.
There is no estimate on when the trails will reopen.
