Dennis Geist's Home Page
I am a professor of geology
at the University of Idaho. I specialize in the study of volcanoes and
volcanic rocks, especially in the Galapagos Islands and the inland northwest
of the United States.
Hot Sort-of New Stuff

page dedicated to present and former Grad
Students in Petrology and Volcanology.

Tired Old Stuff
Check out the prototype of the Geologic
Atlas of the Galapagos (still working on it 4 years later...).
Materials from the Penrose
Conference on the Evolution of Ocean Island Volcanoes, that was held
in the Galapagos in June, 1998.
Courses I Teach
-
Materials and information about Igneous and Metamorphic Rocks
-
An advanced undergraduate/graduate level course
-
My graduate-level class that will be taught next in 2001.
-
An interdisciplinary science core class for Honors students devoted to
the geology of islands, island biogeography and biodiversity, and exploration
of islands.
-
This page contains a table of contents leading to course materials for
Physical Geology.
Other stuff
-
This is a slightly outdated copy of my resume, including publications.
-
I have several seminar talks for colleges and universities, and each year
I visit local schools to talk about volcanoes.
Some Cool Links
The Journal of Petrology
The leading journal of hard-rock geology.
The Zulu Warriors
Each year, a bunch of disreputable people run in the WSU 100 km relay
race. We may be old, but we're slow.
-
Lucky Lab Brew Pub
Go have a beer at my brother's tavern in Portland.
Galapagos Travel
These folks are the best. If you're going to Galapagos, go with them.
-
Bill White
Galapagos site
Bill scooped me and put together a really boss site on Galapagos geology.
The Galapagos
-
A great site with all kinds of hot information on my favorite archipelago.
Mickey's Optic
Stuff
-
Take the spindle stage for a ride.
Kenchron
-
Little Kennie Rubins has things about stuff, some great isotope geochemistry,
and you can even ask him a question!
VolcanoWorld
-
This is the place to start for anything you want to know about volcanoes.
