Preliminary Bedrock and Surficial Geologic Map of the West Half of the Sanders 30' x 60' Quadrangle, Navajo and Apache Counties, Northern Arizona

摘要

The bedrock and surficial geologic map of the west half of the Sanders 30' x 60' quadrangle was completed in a cooperative effort of the U.S. Geological Survey (USGS) and the Navajo Nation to provide regional geologic information for management and planning officials. This report provides baseline geologic information that will be useful in future studies of groundwater and surface water resources, geologic hazards, and the distribution of soils and plants. The geologic map of the west half of the Sanders quadrangle was prepared by the USGS Navajo Land Use Planning Project in cooperation with the Navajo Nation and funded through the USGS National Cooperative Geologic Mapping Program to provide connectivity to the regional geologic framework of the Grand Canyon area of northern Arizona. The geologic map will benefit local, state, federal, Navajo, and private land resource managers who direct environmental and land management programs such as range management, biological plant and animal studies, flood control, water resource investigations, and natural hazards associated with sand dune mobility.
