X Marks the Spot: #12

By Lorraine A. Manz

The landforms marked with Xs are more commonly associated with the Desert Southwest and similar places than with the Northern Great Plains.  That said, there are several locations around the state, mostly in the eastern half, where these landforms are common and are generally associated with glacial lake plains.  Others are derived from older sediments but all were formed by the same natural process.  When you have identified the features marked by the Xs, submit your answers using the form below:.

(1) What are the landforms marked by the Xs?
(2) By what natural process were they formed?
(3) And for an honorable mention… Why are most of these features associated with glacial lake plains?
