Crews were on scene of a crash in Hidden Valley that happened just after 9 p.m. at the intersection of Pembroke Drive and Man of War Drive.
Authorities say they were called out for a possible rollover of a four by four. When they arrived it looked like the vehicle had rolled down a hill.
Four people were in the vehicle at the time of the crash. One is in critical condition.
They say they had to remove all four people from the vehicle.
Washoe County Sheriff's Office and Story County Sheriff's Office responded, as did the hasty team and a Raven helicopter.
