“In the tide pools — many of them, particularly about Thatcher’s Island, curious natural aquariums —the botanist can study and admire a great many species of algae. After one of the many north-east storms, so frequent on this coast during the spring and autumn, he will be well repaid for clambering over rocks and wading through pools along the shore searching for them.”
Dr. Henry Leonard
Pigeon Cove and Vicinity, pub. 1873
This pool is found on the far southwest corner of the island. Located beyond where the seagulls hang out it is available during low and mid-tides.
