Located within the 105-acre Ralph B. Clark Regional Park, the interpretive center tells the prehistoric tale of the area with its extensive fossil collection. Much of the collection dates from over 1 million years ago with some fossils as “young” as 10,000 years old. Most of the collection was acquired during excavations for sand and gravel from the area for construction of the Santa Ana and Riverside Freeways from 1956-1973. Admission to the center is free and it is open Wednesday through Sunday.
The park and
surrounding area was once home to marshes, grassy meadows and vast woodlands
that supported a variety of life, to include mammoths, giant ground sloths,
camels and bison. The county acquired
the land in 1974, and the interpretive center opened in 1988. The center
educates the public about the county’s prehistoric era through exhibits,
educational programs and guided tours.
Visitors can also observe archaeologists and volunteers as they excavate
and prepare fossils for study and exhibit.
Once known as the Emory Borrow Pit and the Los
Coyotes Regional Park, it was re-named after a popular Orange County
supervisor, Ralph B. Clark, in 1987. The
center includes a large mural of ice age animals painted by Mark Hallet, and a 9-million-year
old baleen whale skeleton, one of the few complete skeletons on display
anywhere. It also has various
prehistoric mammal skeletons and fossils on display as well.
learning about the area’s prehistoric past, you might enjoy spending time in
the park which offers picnic areas, playgrounds, tennis courts, shelters, beach
volleyball courts, and fishing in its large pond.
