Fractured Shale Stone

These naturally fractured shale stones are hand-collected from the tidal shores of Cobscook Bay in Pembroke, Maine, and Passamaquoddy Bay near Eastport. Shaped by centuries of tidal action, these smooth, layered gray stones showcase the geological history of Maine’s rugged coast. Their fine texture and natural cleavage make them ideal for aquariums, terrariums, educational geology kits, and coastal craft projects. Sustainably gathered and rinsed to remove excess sediment, each collection offers a unique glimpse into the dynamic processes that shape our intertidal environments.

Tidepool Tim says, "A fine collection of shale shards originating as marine sediments millions of years ago. Shale is often the substrate containing fossils from the Devonian in the Downeast region of Maine! We find fossils here by cracking open shale where the rocky beach meets the eroding soil shelf along the shores."
