It’s really amazing to think about the people who lived here so long ago. Read on to learn more!

Lake Abert is a large but shallow lake in Lake County, Oregon. Due to its alkalinity, no fish can live in it. However, it's quite popular with shorebirds who eat the abundant brine shrimp that live in the lake. Most of the visitors to this area are birdwatchers who come to watch those birds as they migrate.

This lake was not always alkaline. Long ago, it was a lake like any other. In fact, it supported a dense population of early humans for thousands of years.

These ancient people fished from the lake and hunted the mammoths, bison, horses, camels, and mountain sheep that came to drink from the lake. Later, as this and other lakes shrank, people were still able to support themselves by hunting the small mammals that lived in this area.
We don't know much about the people who lived in this area, but they left evidence of their lives behind.

In fact, historians believe that people lived in this area starting at least 11,000 years ago, and continued to live in this area until the mid-1700s.
