Scarlett Point (Scarlett Stacks)

Nature reserve on the coast south of Castletown, combining Carboniferous Limestone and volcanic rocks (the only volcanic rocks on IoM). The limestone formed in a shallow tropical sea; the volcanic rocks record eruptions on the seafloor. Sea stacks and wave-cut platforms provide excellent rock exposures at low tide. WHY COLLECT HERE: (1) FOSSILS: The limestone beds contain crinoid stems, brachiopods, and corals — the same marine fauna as Turkeyland but in coastal exposures. Loose blocks on the beach often have fossil cross-sections visible. (2) VOLCANIC ROCKS: The dark volcanic rocks (basalt) contrast dramatically with the pale limestone — you can literally see ancient eruptions preserved in the rock record. (3) NATURE RESERVE: The area is rich in wildlife too — look for choughs (rare crow-like birds with red beaks) and seabirds. This is a nature reserve so collect only from loose material, don't hammer in-situ rock.
