At Thief River Falls, which is in the region once covered by Lake Agassiz, a considerable deposit of clay 4 or 5 feet thick was used for brick many years ago. The best clay is now nearly exhausted. Excellent brick were made, and, if other alluvial clays are found, they may be suitable for development. (Clays and Shales of Minnesota, Frank F. Grout and E. K.
