At left, Mineralogy '98 pauses in the glow of a late autumn sunset at Friendship,
Maine. Left to right in the front are Karalyn Parzych, Will Tackaberry,
and Marylee Murphy; in the rear are Logan Perkins, Dave Fuente, Michael
Eller, Anna Randall and Paul Dante.

These pages provide previews of several field trips conducted through
the Department of Geology at Colby. The first link is to scenes from four
separate field trips that are taken by students in the introductory physical
geology course, to study bedrock, glacial and coastal features, as well as modern
stream processes.
The field trip to Hartford is a Departmental trip that has been run
in association with GE141 ("Interpreting Earth History"), while that to the Pineo
Ridge (Blueberry Barrens) of eastern Maine is part of the glacial and Quaternary
geology course field experience. Other virtual field trip pages are planned.
At left, Colby students climb in the alpine zone (above
treeline) along The Knife Edge on Katahdin in Maine, the second-highest peak in
the northeastern United States and third-highest in the northern Appalachians.
This sharp-crested ridge, called an arête, was carved by glacial erosion into the
granite of the Katahdin Batholith, a body of rock formed in the Devonian Period
of earth history (some 380 million years ago or so) by melting of pre-existing
silica-rich rocks.
Katahdin is about a 3-hour drive from the Colby campus, and has been the
occasional locale for geology field trips in several upper-division
courses.
At the right, Colby glacial and Quaternary geology students pause during
their search for the ultimate moraines in eastern Maine on a field trip in April,
2001. Laura Wilcox, Will Tackaberry, Melissa Trout, Anna Randall, Sandor Nagy
and Paul Dante had just finished eating lunch and were getting ready to tackle
the Big One at Pineo
Ridge.
The granitic boulders that dominate the moraines in this area form impressive
landforms readily visible since they've been cleared for commercial blueberry
cultivation.
