Maine Geology

Visited Maine last week. Very cool geology. The rocks exposed through erosion (granite & gabbro) create chunky blocks. Ribbons of quartz streak through the igneous gabbro. When the massive glacier retreated from the northern US at the end of the last ice age (~10,000 years ago), it left large boulders that stick out like a sore thumb.
