Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1903 edition.

The mesa runs out to a point near the mouth of the North Fork, the country to the west being of a generally level nature.

Work was continued without cessation throughout the month of June and in July. The topographic mapping was placed under the supervision of Mr. Jeremiah Ahern and was completed September 30. Mr. A. L. Fellows was in charge of the engineering features, and ran three level lines across the mesa to the water's edge. He also made special examination of the bottom of the canyon, which had never been explored. In this he was accompanied by Mr. W. W. Torrence. On October 17 and 18,1901, an examination of the geology of the region was made by Mr. Whitman Cross, of the Geological Survey, for the purpose of ascertaining the formations which would be penetrated by a tunnel piercing the divide by the shortest possible line, and his report is appended (pp. 148 to 149).
