Morrison Cove
...look carefully at the exposed bedrock, and you will notice parallel grooves on the surface of the rock. These glacial striations were left by the ice sheets that shaped the complex coastline of bays, peninsulas and islands of Cobscook Bay.
Welcome
Cobscook Shores is a system of 15 parklands dispersed along the southern and western shores of Cobscook Bay from Whiting to Lubec. The parklands are privately owned by Cobscook Shores Inc., a family funded Maine charitable foundation.
The parklands offer public access and recreational use including walking, picnicking, hiking, biking, camping, and paddling in Cobscook Bay.
The name "Cobscook" is derived from Kapskuk, a Passamaquoddy word meaning "place where the water looks like it is boiling."
Welcome to Morrison Cove, a place shaped by glaciers where we can learn about sustainability from the trees overhead and the rockweed at our feet.
The Bay
As you walk along the shore of Morrison Cove, look carefully at the exposed bedrock, and you will notice parallel grooves on the surface of the rock. These glacial striations were left by the ice sheets that shaped the complex coastline of bays, peninsulas and islands of Cobscook Bay. About 25,000 years ago, this place was covered by an ice sheet 1˝ miles thick. Rock and gravel trapped at the base of the ice sheet left grooves in the bedrock as the ice retreated about 15,000 years ago.
The People
As you walk through the woods along the Bay-to-Bay trail, you can see the diversity of the region's coastal forests. These forests provide the raw materials that Passamaquoddy people have used for generations to make everything from canoes to wigwams to baskets. Birchbark canoes are shaped with cedar planks and ribs. and held together with spruce roots. Ash splints and cedar bark are woven into baskets, bags, and mats. Maple is perfect for canoe paddles. Take a trip across the bay to the Passamaquoddy community at Sipayik (Pleasant Point), and visit the Waponahki Museum to learn more about the Passamaquoddy and see examples of their art and crafts.
Maine's forests are under threat from invasive species like the emerald ash borer. You can help protect these forests: don't bring firewood or live trees from out of state.
Conservation
Rockweed (Ascophyllum nodosum) is one of the most important organisms in Cobscook Bay's intertidal zone. It shelters more than too marine animals, including lobsters, crabs, and juvenile cod and pollock. Shorebirds feed on small critters in the rockweed, and it consumes carbon dioxide, reducing ocean acidification.
Rockweed has long been used as fertilizer, and is commercially harvested today for fertilizer, nutrtional supplements, and livestock feed. Local landowners, the Maine Department of Marine Resources, the Rockweed Coalition, and commercial harvesters are working to balance rockweed protection with the economic benefits of the harvest. At this time, commercial harvesting of rockweed is not permitted on Cobscook Shores sites.
