A 40-year-old woman and her 19-year-old son were rescued from a Mount Lemmon trail by helicopter Sunday afternoon after one was unable to complete the hike.

According to Pima County Sheriff’s Deputy Thomas Peine, the mother and son set out to hike from the top of Mount Lemmon to Catalina State Park using the Lemmon trail. Three hours into their trip, the mother became dehydrated and exhausted and could not complete the hike.

A 911 call was placed around 3:20 p.m. and the Pima County Sheriff’s Department sent out a rescue team.

The pair were airlifted off of the mountain and flown to Catalina State Park where they were evaluated by Golder Ranch Fire.

The mother was treated for dehydration and was able to return home with her son.
