Summary:

Palynoflora studies suggest a basal Liassic or possibly late Rhaetic age for the Shuttle Meadow Formation and a Liassic or Sinemurian age for the Portland Formation, which is stratigraphically separated from the Shuttle Meadow by at least 2,500 ft (750 m) of sediment and basalt flows, including the Holyoke Basalt, East Berlin Formation, and Hampden Basalt. Age is Early Jurassic.
