Greers Ferry Dam Calyx Core
Foundation rock underlying Greers Ferry Dam is revealed in these
specimens of 34" Calyx cores which were cored in 1957. This rock is a
hard, fine grained, shaly sandstone belonging to the Atoka formation.
The Dam is founded on alternating beds of sandstone and shale.
Calyx holes were drilled during preliminary investigations of the
foundation rock in the Dam site area and served several purposes. The
deep open Calyx holes themselves reveal the true nature of the
foundation rock and are inspected by geologists who are lowered into
them to map features such as bedding planes. JOint systems, fractures,
cavities, water inflow and rock quality.
These specimens of 34" Calyx cores represents but a small portion of the
total 309 feet of Calyx core that was extracted in the Dam area. The
deepest Calyx hole was 128 feet deep.

Presented to the Sesquicentennial Committee at Little
Rock, Arkansas - June 1986.
