GEOLOGY OF THE NORTH UNIT
THEODORE ROOSEVELT NATIONAL MEMORIAL PARK

By WILSON M. LAIRD

The North Unit of the Theodore Roosevelt National Memorial Park is at the edge of the glaciated portion of the Missouri Plateau. Because of this situation there are a number of interesting drainage changes which have taken place in and nearby the Park. These changes and their influence on the topography of the Park area are considered in some detail.

The geologic processes responsible for the formation of various land forms are described. Several diagrams and photographs illustrating the drainage changes and the geologic processes at work in the Park are included.

A list of references for further reading is appended at the end of the report. A road log describing the geologic features to be seen along the roads of the Park is also given. A short statement of the more interesting historical highlights of the region is included.
