The well at the mouth of the creek nearly a thousand feet deep disclosed evidence of the ancient waterfall heretofore mentioned. Near the Mihan farm in the northeast quarter of section 34-23-58 the discovery of oil sands and gas was made. The quantity is small, the depth thereto is shallow, less than one thousand feet, but through all the years there has been a steady flow of gas from the four inch pipe in the well. It is in sufficient quantity to burn when confined to a small hole.
The Prairie Oil & Gas -- a subsidiary of the Standard Oil -- drilled to the south of the county and are operating in the Goshen Hole to the west. The Centennial well and the new well just spudded in by an Ohio company are within ten miles of the west county line. A well at Agate about twenty miles from the north county line is down some distance with good prospect. Oil and gas are found seeping from the ground in some parts of Scotts Bluff county and there is evidence of one "very old structure" a part of which is within the county and of several "newer structures" in whole and in part within the county limits.

The Wildcat range has many beds of excellent volcanic ash, one being about eight feet thick and of great purity. In the Owl creek country there are magnesium outcrops that are valuable. Wonderful and extensive beds of gravel are here and there throughout the county. Some of these are of the quality and color of the famous Sherman hill gravel used for
