This guide provides information on the geology of Bald Mountain, an outstanding example of an unvegetated mountain summit in western Maine. Topics include the petrology of the metamorphic rocks exposed on the mountain (layered quartzite and schist), which preserve evidence of their sedimentary origin (graded bedding, cross-bedding). There is also information on the glacial history of the area, as ... Full description.

This guide provides an introduction to the glacial landforms and other complexly eroded features seen in Grafton Notch State Park, which is located in southwestern Maine. There is a detailed discussion of the glacial history of the area, which features steep gorges, waterfalls, eskers, an ancient glacial lake, and other landforms superimposed on a terrain of Silurian metamorphic rocks and Devonian ...

This guide introduces visitors to the glacial and postglacial geology of the White Mountain National Forest in western Maine. The discussion covers the timing of the glaciation (the Laurentide Ice Sheet, 25,000-13,000 years ago) and the numerous features left behind: erosional features such as high cliffs, grooves and striations; depositional features such as till, erratics, and glacial lake deposits; ...

This guide introduces visitors to the sediments and geologic histories of Mile and Half Mile beaches in Reid State Park on the coast of Maine. Topics include the source of the sand presently found on the beaches, the origin and migration of beach deposits, dunes, and marsh peat deposits as sea level has risen, and some history of the area. Some suggested activities for visitors include observing grain ... Full description.

This guide introduces visitors to the geology of the Marginal Way, a mile-long public footpath in the southern coastal town of Ogunquit, Maine. Topics include bedrock geology (Silurian quartzites and phyllites), later intrusives (sills and dikes, mainly of basalt), and evidence of glaciation (striations). Suggested activities include observing graded bedding in the bedrock, estimating the ages of ... Full description.

This guide will introduce hikers to the rocks and geologic history of the Front Range as seen along the trails west of the National Center for Atmospheric Research (NCAR) Table Mesa facility in Boulder, Colorado. Field trip stops include outcrops of rock formations representing inland sea deposits (Dakota, Benton Niobrara, Pierre) laid down before the uplift of the present Rocky Mountains about 70 ...
