The San Joaquin Valley, the southern half of the large flat mountain-bound interior of California, has undergone many changes.

The Pacific Ocean birthed this Valley we Maderans call home about 65 million years ago when it began to intermittently flood parts of the region. Eventually sediment from the sea and the rise of coastal mountain ranges choked off the Valley from its mother 60 million years later.

Around 2 million years ago, glaciers started to transform the Valley from a salty oceanic remnant into a freshwater lake.
