Abstract: This seminar will focus on the various aspects of
karst, including caving, exploration
techniques and case studies. The
presentations will be given by some of the best professionals in
the
field. Students will be presenting their research and a career development
seminar will be given
by several members of the AEG Young Professional
s Committee to assist them in professional
employment skills. The Mamm
oth Cave area is a very complex karst terrain, with the St.
Genevieve
and St. Louis Formations of Mississippian age forming the principal karst a
quifers.
The dissolution conduits formed here are typical of most kars
t aquifers, forming a convergent flow
system, not unlike surface strea
ms.
Flow velocities in the conduits range from 30 to 1300 feet per sec
ond, with the highest order
conduits commonly as much as 50 feet in wi
dth. On reaching the stratigraphically higher, more
soluble units, the
streams sink near the margin of the sinkhole plain. From there the groundw
ater
flows in subsurface conduits through the upper St. Louis and St.
Genevieve units, to emerge as
springs along the entrenched Green River
.
More than 400 dye traces within an area comprising parts of twenty-t
wo 7.5-minute quadrangle
maps have given us an unparalleled understand
ing of this karst area. Within it there are 22
groundwater/surface bas
ins and major sub-basins. The groundwater dye tracing techniques used
in this area will be discussed along with their practical use.
