I came across some picture of the Palouse hills. I found out that there were also grasslands in this region. Most of the grasslands have given way to farming and other development.

I am showing just a bit about this region.

The map. US Map of The States  by, the Environmental Protection Agency. I drew the little somewhat of a circle to show where the Palouse region is located.

The Palouse region is in Idaho, Washington and Oregon.

All of the pictures are from Wikipedia Commons, except for this first one. It is of the grasslands  by, National Park Service.

These next two pictures are of fields. The first is early summer and the second is of autumn. They were taken by, Dsugan from Kamiak Butte, Washington.
