Yes, please take some seaglass from this cache for your own collection!
During the great quarantine clean of 2020, I discovered my rock collection, assembled over years of studying geology in college and just picking up cool rocks along the way. Having way more rocks than we knew what to do with, we thought it would be fun to share them with fellow geocachers in a new series along the Merrimack River: the rock collection! These 15 caches are hidden in a linear fashion along a portion of the Bay Circuit Trail which can be walked or biked, across AVIS's Deer Jump Reservation (and a couple other reservations as well). The containers vary in size, but each should be an easy find. Each one highlights a different really cool rock. Tradeables may not be left in these caches, though if you collect rocks yourself you can keep a rock from some (but not all) of these caches. Coordinates for a possible trailhead are provided, though there are many places you could begin your hike.
Seaglass
Alright, so this is the not technically a rock... but I've still always included it in my rock collection because of the powerful weathering and erosive forces that sculpt this glass just as they sculpt seaside rocks. Seaglass forms when shards of broken glass are tumbled around in ocean currents and waves and ground along against sandy, rocky seafloors. Over time the sharp edges of the glass are broken off and the glass's surface becomes smooth and milky. This seaglass was found over many years along the coast of Maine, on the islands of Casco Bay (near Portland). Please, take some seaglass from this cache for your own collection!
