Tar Pit Excavation on Public View

July 27, 1993|NONA YATES

The annual summer excavation of La Brea Tar Pit 91 is under way. Visitors to Pit 91 can observe the excavation from a viewing station located above the pit through Aug. 29. This is the only excavation of its kind on public view in a major U.S. city. In 1992, excavators, many of whom are volunteers, uncovered a record 1,117 specimens.

No dinosaurs, a la "Jurassic Park," are found in the pit. They disappeared 65 million years before the La Brea fossil record began. The remains of mammals such as saber-toothed cats and giant ground sloths have been recovered there, giving a clue to what life was like 38,000 to 10,000 years ago in the Los Angeles area.

The viewing station will be open Wednesdays through Sundays from 10 a.m. to 4:30 p.m. Fossils recovered from the tar pits are displayed at the George C. Page Museum nearby. Call (213) 936-2230.
