One of the climbers identified by the sheriff's coroner's office was 29-year-old Eduardo Escobar. The two people were found dead by firefighters after they were involved in a climbing accident.
The two people died while climbing a rock face.
There was a small amount of rain earlier in the day, but officials didn't say if it was related to the deaths.
