Geology Field Trip
Contact & More Info
Join geologist Erika Vye as we read the wave-washed black and red rocks of the north shore to learn how the Keweenaw was formed over one billion years ago. Imagine a rugged, treeless landscape; massive lava flows interbedded with large pieces of rounded boulders, pebbles, and gravel eroded from what was then the impressive Huron mountain chain nearby. After exploring the black rocks at the shoreline, we'll walk the Keweenaw Shores trail and back. Then we'll hop into our cars to drive a few miles east to walk the red rock conglomerate shoreline. Plant communities distinctive to these environments will be pointed out as we hike. Bring along snacks, water, a picnic lunch if you wish, and wear sturdy footwear for hiking. Walking poles will be especially helpful on the conglomerate shoreline.
From Eagle Harbor follow M-26 east about six miles to Esrey Park along Lake Superior, less than a mile past Brockway Mountain Drive's west entrance. Look for the large MNA Event sign in Esrey Park, where we will meet.
