View ancient Anza-Borrego and see the
great range of plants and animals that
lived here millions of years ago. Today,
where you see a desert, was once the
shoreline of a great ocean. Over time
the ocean transitioned to an inland
sea and later a delta formed by the
Colorado River. The delta shaped an
entirely new landscape of forests, rivers,
and lakes. Eventually the area became
a great savannah that supported a vast
array of Pleistocene plants and animals.
Today the Anza-Borrego Desert has yielded
the greatest collection of Pleistocene
fossils in North America. Step through
the virtual window to see camels, llamas,
mammoths, sloths, cats, wolves, bears,
and horses...as well as ancient marine
life that that ranges from seals to
shells.
