A GEOLOGICAL RECONNAISSANCE IN HAITI 733 
range, especially near Cerca Carbajal. All along this range the 
prevailing dip is to the south. 
Tippenhauer’ in a section north of Gonaives determined a thick- 
ness of 16,500 feet for this limestone series. ‘There is probably 
duplication at this place. A section the writer measured between 
Hinche and Cerca Carbajal showed a thickness of 13,000 feet but 
later the conclusion was reached that there was good evidence 
here of duplication. There is, however, at least in this section, a 
Fic. 1.—Fine-bedded, compact, foraminiferal limestone in quarry near Gonnaives 
thickness of about 6,000 feet exposed. Southeast of Port-au-Prince, 
on the road to Fucy there is, however, an unduplicated section of 
limestone whose thickness is at least 8,000 feet (see Plate V, Sec- 
tion C, south range). 
This same limestone on the south side of the Gran Cordillera 
in Santo Domingo was called Cretaceous by Gabb,? being included 
by him with other limestone of undoubted Cretaceous age. Tippen- 
hauer has called it Miocene and Pliocene and his mapping has been 
done largely on the basis of the color of the rock. The conclusion 
that it is Eocene and lower Oligocene, prior to any paleontological 
work, is based on its striking similarity to the Jamaica and Cuban 
occurrences and also because of its position relative to overlying
