The Tisbury Vision Council is offering a unique opportunity to learn more about Lake Tashmoo with a guided walking tour this Saturday, Nov. 7 (rain date Nov. 8). The tour begins at the Tashmoo Overlook promptly at 10 a.m. and will last about two hours.

Parking is available on the road through the stone pillars east of the Tashmoo Overlook. Do not park at the overlook or along the highway. Participants should wear warm, waterproof footgear, dress appropriately for the weather, and bring water.

Saturday’s tour will explore the 23-acre parcel of land that stretches from the overlook to Lake Tashmoo, including the large open field bordered by ancient stone walls, the sledding hill, the recently restored Tashmoo Spring Building, an amphitheater, and a freshwater pond with an abandoned herring run.

Former Vineyard Conservation Society executive director Bob Woodruff will talk about the area’s glacial formation and ecological features. Randy Jardin, a cultural resource monitor for the Wampanoag Tribe of Gay Head (Aquinnah) will also be on hand.

Discussion will continue after the walk at the Tashmoo Spring Building, with refreshments served.
