Alameda Native History Project Shellmound Model

For the first time, ever, an entirely independent research project, led by a Native American descendant, has produced a tangible representation of pre-contact Native American Spirituality and Engineering.

About the Alameda Native History Project:

The Alameda Native History Project is an independent, Native-led research project focusing on discovering unknown or misunderstood Native History, and educating the public through applied art and science.

What is a shellmound?

A lot of people wanted to know, “What is a shellmound? What does a shellmound look like? How big were the shell mounds?”

While one could spend time curating schematics, maps, and historical images…. there are truths which reveal themselves.

The best way talk about shellmounds is to show them.

Basic traits of a shellmound….

  1. Shellmounds range anywhere from about 3 to 70 feet tall.
  2. Shellmounds have a diameter of about 10 to 300 feet.
  3. Shellmounds have a distinctive domed shape,
    usually with a pavillion, and a ramp or walk-way down one side.
  4. Each shellmound accounts for hundreds to thousands of Native Americans.
    Around 2,000 people were buried in the Emeryville Shellmound.
  5. Shellmounds are not trash heaps.
  6. Shellmounds are burial grounds.
  7. Shellmounds are sacred burial structures, built by the first occupants of the San Francisco Bay Area.
