126 FLORIDA GEOLOGICAL SURVEY-TWELFTH ANNUAL REPORT 
color and in hardness. The brown limestone at the depth 1,022, 
of which only one sample was preserved, is not unlike that of other 
deep wells in peninsular Florida. 
That part of the peninsula in which the Eocene formations so 
far as known lie at a depth of more than 200 feet below the sea 
level, includes a small area in the northeastern part of the State 
and the whole of extreme southern Florida as well as a coastal belt 
west of the Apalachicola River. The depth at which the Eocene is 
known more or less definitely, is indicated at several localities 
within this large area, although the data is as yet very limited. 
There is in particular complete lack of information as indicated 
by the question marks placed on the map in the southern part of the 
Lake Region where the older formations may be expected to lie 
rather close to the surface. The following description of samples 
from wells within this area has not been heretofore published. 
Well samples from the well of the Okeechobee Company, 
Okeechobee, Florida. Well located on lot 5, block 134, approxi¬ 
mately 34 feet above sea, and about 14 feet above the level of Lake 
Okeechobee; 10-inch pipe rested at 150 feet; 8-inch pipe rested at 
307 feet; 6-inch below this level, amount of 6-inch casing not 
known. 
0-2 feet, fine gray sand and soil. 
2-12 feet, fine sand, chocolate colored some of it indurated with organic 
matter, ordinary hard pan. 
12-15 feet, gray or slightly brownish indurated sand (not marl). 
15-38 feet, gray sands. 
38-41 feet, the sample preserved consists chiefly of black clay containing 
considerable sand, one fragment of shell, but aside from this 
no indication of marl. 
41-56 feet, sandy shell marl, shells mu ah broken. 
56-62 feet, shell marl, pecten, barnacles, etc., marine shallow water marl. 
62-65 feet, gray, sandy marl with broken shell similar to No. 6. 
65-81 feet, coarse clear grain sand and broken shell. Ostrea, turritella, 
bryozoa. 
81-87 feet, sandy marl with broken shell. Pecten. 
87-94 feet, very sandy olive colored marl. 
94-139 feet, light gray incoherent sand. 
139-158 feet, light colored sandy marl with shell fragments. Pecten. Oc¬ 
casional phosphate pebbles, black and shiny. 
158-175 feet, olive green sand or very sandy marl. 
175-212 feet, olive green clay with black smooth shiny pebbles, phosphatic.
