STRATIGRAPHY 



Grand Manan . — The 

 island of Grand Manan is 

 situated 4 miles southwest 

 of Quoddy Head, the most 

 easterly point in the Uni- 

 ted States. It is 15 miles 

 long and 6 miles wide in 

 the widest part. To the 

 east and south are numer- 

 ous islands and reefs. 



Grand Manan was first 

 visited by a geologist — 

 Abraham Gesner — in 1838, 

 then by Bailey, 1 Verrill, 2 

 and Ells. 3 Bailey visited 

 most of the adjoining 

 islands and gives the best 

 description of the geology.
