Geology and water resources of a portion of the Missouri river valley in northeastern Nebraska . water in the loessand sand and gravel deposits, and from these springs issue, especiallyat the contact with impervious beds. Many flow from the outcrop-ping edge of the top of the Pierre clay, which extends along the sidesof the valley slopes. Talus from later formations often covers theclay more or less in the outcrops and sometimes carries the springwater to lower levels. In some parts of the county the upper surfaceof the clay is very uneven as a result of erosion. As in adjacent counties the number of springs is very great, prac-tically every little ravine along the Niobrara, Verdigris, and Bazilevalleys being fed by a spring, large or small. Only a few can benoted: Springs just southwest and northwest of Verdigre could bepiped to furnish an abundance of water for the town. The La MontSprings, about 2 miles south of Niobrara, are quite strong. A springat the place of R. F. Stout, sec. 5, T. 30, R. 5 W., south of Center, is U. S.
