An Event On June 10th Will Bring The Past...

To A Present Near You!!!

For 4.5 billion years the earth has been orbiting a small star that we call the Sun.  During this time the earth has fostered many remarkable things: the creation of the first organisms, plate tectonics, trilobites and invertebrates, volcanoes, mountain building, cave formations, diamonds, opals, rubies and the extinct creatures we have come to know as Dinosaurs.

The earth has held many amazing things throughout its life; however, many of these geological items have been lost to time or buried beneath the earth’s surface, forever locked away from most of civilization—until now!

On June 10th, the Madigan Library will be opening its doors to an exhibit eons in the making: Rockhounds: Digging The Ground Beneath Us! This one-day exhibit will feature geological items that run the entire gamut from precious gems and stones to dinosaur fossils! 

A large piece of the mineral kyanite on display at the Madigan library.  This piece is from a private collection and once belonged to the Natural History museum at the Smithsonian in Washington, DC.

This exhibit was made possible by faculty and staff of the Pennsylvania College of Technology.  Without them we would not have an exhibit with nearly as many interesting and exciting specimens!

Be sure to read on below to learn more about what kind of items will be at the exhibit!


Ferns, Trilobites, Dinosaurs and More!

Fossils are some of the most interesting items of the geological past. They capture our imagination and allow us to peer into the past to see what life was like millions of years ago.

This section of the exhibit will feature many fossilized specimens from many eras of the geological past. There will be fossils from ancient seas, fossils from ancient forests and large fossilized bone fragments from a certain "King of Dinosaurs." The fossil exhibit will be sure to inspire young minds to head out and find a piece of the past.


Minerals, some formed over millions of years, range from common iron to the rare and precious diamond. This section of the exhibit will feature several specimens from the mineral family.

Quartz, Kyanite, Aventurine and Jasper are but a few of the minerals that will be on display.  Minerals can form in pockets or inside of rocks called Geodes; they form delicate stalagmites and stalactites in caves, and several minerals are often turned into jewelry.

One can even find local mines that are open to the public, making mineral hunting an exciting (not to mention lucrative) pastime!


While not as thrilling as fossils or as interesting as minerals, rocks have their rightful place in rockhounds exhibit.

Rocks tell the tales of our geological past. Many times we can date how old fossils are by the layer in which they are found within a rock strata. Rocks form mountains and hold information about events that occurred millions of years ago. It was the information locked within rocks that told us the approximate time when the dinosaurs went extinct and what caused their extinction (see K–T boundary).

Rocks is our final section that will be featured within the Rockhounds exhibit.
