The Southeastern Coastal Plain: An Overview, Lee J. Florea, H L. Vacher Jul 2009

The Southeastern Coastal Plain: An Overview, Lee J. Florea, H L. Vacher

Lee J Florea, PhD, P.G.

Florida enjoys the highest density of large springs in North America (Scott et al., 2004); Silver Springs is just one of the 33 first-magnitude springs (mean flow greater than 100 cfs (2.8 m3/s), and there are hundreds of smaller springs (Fig. 6.2; see Meinzer, 1927, and Scott et al., 2004). They are supplied by spectacular underwater caves that are internationally recognized in the cave-diving community. Less well known are the many air-filled caves of the region (see Florea, 2006; Moore, 2006; Lane 1986). Though generally smaller than their aquatic counterparts, their beauty can rival the world’s best show caves. This …


The Cumberland Plateau Of Eastern Kentucky, Larry C. Simpson, Lee J. Florea Jul 2009

The Cumberland Plateau Of Eastern Kentucky, Larry C. Simpson, Lee J. Florea

Lee J Florea, PhD, P.G.

Eastern Kentucky contains almost the same Mississippian limestones that appear at Mammoth Cave in south-central Kentucky (Chapter 3). To the east these strata dip below the Appalachian Basin and reappear as the Greenbrier Group in the Virginias. The limestone outcrop in eastern Kentucky follows the western margin of the Cumberland Plateau and forms a ragged ribbon of karst that is continuous from southeastern Ohio through Kentucky and Tennessee and into northern Alabama. There are more than 2,000 documented caves comprising over 470 km of surveyed passage in the Kentucky segment of the Cumberland Plateau (Fig. 2.115). At least 14 are …


Caves And Karst Of West-Central Florida, Lee J. Florea, David Budd, Robert Brinkmann Jul 2009

Caves And Karst Of West-Central Florida, Lee J. Florea, David Budd, Robert Brinkmann

Lee J Florea, PhD, P.G.

The real west-central Florida is far from the “Sunshine State” image of white sand beaches and palm trees. Gently rolling hills, dense jungle-like forests, pine and palmetto scrublands, impenetrable cypress swamps, and alligator-laden rivers are more common. Numerous crystal-clear springs offer a glimpse of the hidden world below – a world that could challenge the most imaginative Disney artists (Fig. 6.17).

Geology And Hydrology Of Karst In West-Central And North-Central Florida, Lee J. Florea Aug 2008

Geology And Hydrology Of Karst In West-Central And North-Central Florida, Lee J. Florea

Lee J Florea, PhD, P.G.

The state of Florida is blessed with the highest density of large springs in North America and hundreds of smaller springs where the water from limestone aquifers returns to the surface (Scott et al., 2004). Spectacular underwater caves supply water to these springs. Lesser known are the equally fantastic air-filled caves of Florida and South Georgia (Florea, 2006; Lane, 1986). This paper features these underwater and airfilled caves, explores the impact of changes in sea level on karst in this near-coastal environment, and establishes several geologic and hydrologic characteristics that distinguish karst in the limestones of the southeast from karst …

Cave Levels, Marine Terraces, Paleoshorelines, And The Water Table In Peninsular Florida, Lee J. Florea, H L. Vacher Jan 2006

Cave Levels, Marine Terraces, Paleoshorelines, And The Water Table In Peninsular Florida, Lee J. Florea, H L. Vacher

Lee J Florea, PhD, P.G.

Levels of passages are a common feature of many cave systems around the world. Likewise, coastal and marine terraces are common in coastal plain settings. This paper extends the discussion of cave levels from traditional research sites in the interior lowlands of the United States to the Atlantic Coastal Plains, namely peninsular Florida. Are there levels in Florida caves, and is there a link between the elevation of cave levels, marine terraces, paleoshorelines, and thus the water table, above and below present sea level in peninsular Florida?


Emergency Response Canadian Pacific Railway Canadian Main Line, Barry A. Palynchuk Phd, Michael J. Loehr, Robert W. Badger, Robert P. Conroy, Clive H. Mackay Jan 2000

Emergency Response Canadian Pacific Railway Canadian Main Line, Barry A. Palynchuk Phd, Michael J. Loehr, Robert W. Badger, Robert P. Conroy, Clive H. Mackay

Barry A. Palynchuk PhD

In late June 1998, a major storm event occurred in the Adirondack Mountains in the vicinity of Keeseville, New York about 150 miles north of Albany. This storm resulted in unprecedented damage to the Canadian Pacific Railway (CPR) Canadian Mainline along the shores of Lake Champlain. The storm caused 14 major embankment failures and washouts, numerous minor failures, severe bridge foundation scour and a major mainline derailment.
