Skeletal remains of a body found in Crater Lake National Park are being studied to determine if they are the remains of a California man missing since 1991.

CRATER LAKE — Skeletal remains of a body found in Crater Lake National Park are being studied to determine if they are the remains of a California man missing since 1991.

Park ranger Dave Brennan said a firefighter found the remains in September in the remote Bybee Creek area of the park. But he declined to release details pending further investigation.

Winter snows prevented rangers from reaching the area until this summer, when park rangers began an investigation with the FBI.

Law enforcement officials have contacted the family of Glenn Mackie of Brea, Calif., whose vehicle was found at the Rim Village parking lot in October 1991. His driver's license, keys, passport, cash and toiletries were in the car, but no trace of him was ever found.
