Take the challenge...


Rocks hold secrets to how ancestors lived

The Miwok Indians who once lived along the Delta learned to utilize the area’s natural resources. They collected rocks to make arrows, war clubs and stone knives. Stones like obsidian were used to make arrow points and chipped tools.

Rock collectors have found many Native American artifacts along the Sacramento-San Joaquin Delta.

Take a walk along the Delta shoreline or at a local park and see if you can find a rock that might have once been used as a tool by the Miwok Indians that once lived in the Delta region.

You can make other collections, too. Bring a digital camera on a Delta shoreline walk and take pictures of a favorite type of bird, flower or insect. See how many different species you can count in an hour.


Take a look back to 2015...

A region transformed

Tidal freshwater marsh blanketed by fertile peat soil was all that existed along the Delta shoreline in the late 1800s when farming started on the Sacramento-San Joaquin Delta. now the shores of the Delta support enough agriculture to help make California the fifth largest economy in the world. California produces about 200,000 tons of pears each year, adding $80 million to its economy. That is 25 percent of all pears grown in the united States. about two-thirds of the pears produced are grown in the Delta. area farmers also grow a variety of other crops including asparagus, almonds, pears, pistachios, hay, citrus, alfalfa, corn, tomatoes and more. cattle, sheep and dairy can also be found along the Delta.
