Authorities have located the vehicle associated to the Potts family in a remote area of Redington Pass near Mile Post 11.
55-year-old Belen Potts and 29-year-old son Ernest Potts had not been seen or heard from since July 14.
Hikers in the area located the vehicle that was off the roadway and down an embankment.
The hikers had also located a deceased person in the area of the vehicle.

No one else was located near the area of the vehicle.
Authorities say it is still not known as to how the vehicle ended up down the embankment.
