Geology Classes
Introductory Geology classes are always well attended. One of the most popular is Geology of the Hawaiian Islands, which is participated in by students from a variety of disciplines. Additionally, upper-level Geology courses are especially enjoyable because they involve a lot of hands-on work, both in the field and in the lab.

In the Hydrology course, students get to work with models that demonstrate the flow of groundwater.
In Physical & Optical Mineralogy, students analyze petrographic thin sections under the microscope. The UH Hilo Geology Department has a rock preparation lab, and students are allowed to make their own thin sections if they wish, assisted by a friendly staff technician.

Structural Geology and Field Methods are favorite upper-division classes. Students have the opportunity to learn how to read a Brunton compass, make field observations, interpret data, and create their own maps.
Field Methods students practice using the Brunton compass on Mauna Kea.
Back in the lab, students prepare maps from field measurements.
