Course Description

This course will examine how volcanic, geomorphic, and coastal processes have shaped, and continue to shape, the Hawaiian Islands. The course focuses on volcanism, landform development, and coastal processes. The Hawaiian Islands provide a unique opportunity to study active volcanic processes building the islands in conjunction with geomorphic processes that alter the volcanic landscape. The Hawaiian landscape ranges in age from 25 million years to minutes old. Students have the unique opportunity to study the volcanic processes creating the islands and then see how the soils, landscapes, and coasts have evolved through time.

Course Learning Objectives

· Understand how tectonic activity has shaped the development of the Hawaiian Island – Emperor Seamount chain

· Compare the geological environments on the progressively older Hawaiian islands of Hawaii, Maui and Oahu

· Understand how volcanic, geomorphic, and coastal processes have shaped, and continue to shape, the Hawaiian Islands.

· Use ergodic reasoning to develop an understanding of how the Hawaiian Islands age.

· Evaluate the geological hazard potential in Hawaii with regard tto different volcanic, seismic, and mass-wasting prone terrains.

· Develop the observation and data acquisition skills used in geology.

A $25 materials fee covers the costs of your field notebook as well as the readings packet and fieldtrip guide. You will need to have your field book with you at all times and insure that it is not lost. It will be assessed periodically for completeness, depth of observations and readability. This is your primary source for preparation for exams.

Academic Honesty

Students are expected to conduct themselves according to the guidelines and rules of Lafayette College (see your student handbook) with respect to academic honesty and the preparation of their work for this class.
