About this file
This document package includes geologic logs and drawings from exploratory drilling for the Navajo-Gallup Water Supply Project Navajo Code Talkers Sublateral Reaches 12.1 and 12.2. The logs document soil and bedrock conditions from 11 drill holes located along the project alignment. Details include stratigraphy, lithology, physical properties, weathering, and discontinuities by depth. Agency involvement includes the Department of the Interior Bureau of Reclamation. The project scope involves preconstruction foundation investigations for pipeline design.
