Black Rocks Michigan Shoreline Pendant handmade by Beth Millner Jewelry

Hiking Presque Isle Park, cliff jumping, watching the northern lights, local craft beer... to Marquette locals the term "Black Rocks" is associated with many things. Our Black Rocks pendant captures the natural beauty of this landmark and all the joyful memories made there. But what exactly are these black rocks? And where can a non-local find them?

What are they?
This rock formation is 1.7 billion years old. Known to geologists as metamorphosed igneous peridotite, aka really really old magma flow. These porous rocks are mostly covered by reddish and white Jacobsville Sandstone, but on the north shore of Presque Isle the volcanic remnants jut out over Lake Superior creating a spectacular contrast in the landscape.
On stormy days, the waves crash over the 20 foot tall cliffs and surge up the rock beach. It's a thrill to stand in the splash zone and experience the true power of Mother Superior. Thrill seekers can enjoy calm sunny days too though. People of all ages throw themselves off the cliffs into the frigid waters below.

Where are they?
Black Rocks is located along the northern shore of Presque Isle Park, one of Marquette's most prized natural locations. Less than 10 minutes from downtown, any visitor is sure to have their breath taken away any time of the year by the stunning shoreline. The City has a nice map showing the exact location along with all the other neat features on Presque Isle.
