The Cuba Sandstone is a member of Canadaway Group found in central New York (State). The Cuba is a lenticular (geology) regional formation. It is believed be a small delta formed in the Devonian.[1] This unit is approximately 10 to 40 feet thick.
The Cuba is described as a slightly arkosic, cream colored sandstone. Grain sizes tend to be medium to course. It has been noted to smell strongly of petroleum.[2] The Cuba is formed by three fine grained lensing packets. The lenses are separated by units of interbedded grey shales and thin sandstone beds.[3] The Cuba formation was formed by episodic storm events, up to hurricane strength.
