Answer:
glaciers covered better part of North America including California and it's still evident in San Bernardino Mountains.
Explanation:
The Pleistocene Epoch is typically defined as the time period that began about 2.6 million years ago and lasted until about 11,700 years ago. The most recent Ice Age occurred then, as glaciers covered huge parts of the planet Earth.
Sometimes, up to 30% of Earth was covered in ice. At times this included the better part of North America — California became almost completely entombed in ice. Today, evidence of the glacial takeover can be found as far down as southern California's San Bernardino Mountains.
The variation of sunlight reaching Earth is one cause of ice ages. ... When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.
