The Pawnee Buttes are near Greeley.
They are located about 60 miles north east of Greeley. They are a part of the National Grasslands. The land is much like it was in the early days of Greeley. This part of Colorado is a part of the Great Plains region. Stephen Long thought this area was worthless when he saw it in 1820. He called it the "Great American Desert". He thought that it would be fruitless to try to grow crops here. However with irrigation, the "Great American Desert" has become one of the largest agricultural areas in our country.

The Great Plains Region covers several states.
You can find the Great Plains from Canada to Southern Texas. It covers the most populated areas of Colorado as well as the wide-open prairies.

The Great Plains Region has many resources.
The wide open prairie allows winds to blow freeley so wind turbines are becoming more common to help generate electricity. The area is also where most of the oil is found in the Untied States.
