Water Always Wins

Water’s ancient negotiations with rock and soil created these historic riverbeds, called paleo valleys, that lie hidden underneath us. Because they are more permeable than surrounding material, they are still the pathways that water wants to travel underground. Only three have been discovered so far in California. Hydrogeologist Graham Fogg has a dream: to find more of these paleo valleys and use them as giant drains that can absorb water from today’s heavier winter storms and store it underground.
