UC Davis hydrogeologist Graham Fogg’s ‘Paleo Valleys’, buried along the base of our Sierra Nevada’s western slope, are a potential godsend to groundwater recharge-obsessed Central Valley communities. These ancient, buried riverbeds, dating from the last ice age, are cobble and gravel-filled to depths of 100 feet, can extend for miles underground, and have been proven by Fogg’s team to guzzle flood water as much as 100 times faster than surrounding land. Join Graham and “Down on the Farm” host Tom Willey.
