Geology Department Overview

Welcome to the Geology Department!  Our goals include:

  • Helping students interpret Earth's landforms and correlate how natural resources formed throughout geologic history;
  • Assisting students in learning how geologic resources are utilized by humans and the value these resources provide to humans;
  • Promoting awareness of and active participation in learning, volunteering and completing undergraduate research in programs designed to study and conserve our geologic resources; and
  • Exposing students to the development of life forms on Earth throughout geologic history as documented in the rock record.
