Big Bear Lake's 20,000 Year Old Ancient Lake

Big Bear Lake is a manmade lake, but recent studies have discovered that about 20,000 years ago an ancient lake, much larger that today’s lake, once covered the whole Big Bear Lake valley. This short video tells what happened. This video was produced by Rick Keppler, and hosted by Kim Sweet.
The images for this video were provided by the recently published “Vanishing Big Bear-2”, and from the historical collections of Rick Keppler, and Mark Durban.
“Vanishing Big Bear-2” is a hardbound 8.5” x 11” book. It is available online at www.fascinatin..., and at www.amazon.com..., and at the following retail locations around the Big Bear valley:
Butchers Block
Interiors - on Fox Farm Road
Haus & Home Furnishings
Bear Skins
United Wood Craftsmen
Big Bear Discovery Center
Old Country Store
Big Bear Sporting Goods
Big Bear Lake Visitors Center

Any links to those scientific studies you talk about?

I have not looked for online links. The information in this video was from a report titled "Prehistoric and Historic Environmental Conditions in Bear Valley, San Bernardino County, California". It was prepared by E.I.P Associates of Sacramento, California. in 2003.
