Rocks and Minerals:

from the collection of
Jeff Troupe

June - July 2016

A fascinating collection of rocks and minerals are the latest exhibit of “Beyond Books: Community ArtShare” at T.B. Scott Free Library, which you can view through the end of July.

Featured collector and current Merrill resident Jeff Troupe has been collecting interesting rocks and minerals for over 17 years.  His interest in the field culminated in a degree in geology from Sacramento State University.

Metamorphic rocks--rocks changed by extreme heat and pressure--are Jeff’s favorite.  Many of the specimens on display are metamorphic rocks collected from Tiburon north of San Francisco and are around 450 million years old.


Many of these San Francisco-area specimens date from before the 1906 earthquake.  Among them, quarry rocks used to build pre-earthquake San Francisco are particularly interesting.


Jeff Troupe’s collection will be on display on the library’s second floor through July.  T.B. Scott Free Library’s “Beyond Books: Community ArtShare” features new exhibits on an ongoing basis. The program was made possible by a $10,000 grant from the Mead Witter Foundation, Inc. of Wisconsin Rapids.
