Welcome to the Ohio Division of
Geological Survey
Interactive Map of Ohio Surficial Geology
The
interactive map of the "Surficial geology of Ohio"
depicts the thickness and stratigraphic sequence of geologic units
(materials such as till, gravel, sand, silt, and clay) from the land
surface down to and including the uppermost buried-bedrock unit. The
available areas are continually updated to include all published maps
for Ohio. Data sources include county soil surveys, ODOT boring logs,
engineering logs, water-well logs, and field data. The
reconnaissance-style map can be used to quickly obtain the surficial
geologic framework of the area and will benefit environmental
scientists and engineers as well as land planners, researchers, and
local property owners.
Mapping was funded by a severance tax on Ohio's mineral industries
including coal, oil and natural gas. Additional funds were obtained
from the U.S. Geological Survey, National Cooperative Geologic Mapping
Program (STATEMAP component).
Print-on-demand, full-color, wall-sized (1:100,000 scale) paper version
of this map, with explanatory text and CD-ROM containing digital data,
are available from the Division of Geological Survey.
