Pleistocene
"Ice Age" (50,000 Years Ago)
Coastal emergence caused shallow
bay muds to become savannas and plains. Saddleback Mountain rose
and was carved into valleys and foothills by streams. Forty-two
Ice Age animal species lived in these valleys and their fossils
have been preserved under Alicia Parkway and Costeau Park.
Animals with an asterisk (*) are still living in Laguna Hills today.
