Hydrogeology of theMississippian scarp-slope karst system, PowellMountain, Virginia
Abstract:
Mississippian carbonates on scarp-slopes of Powell Valley show few surficial karst features, yet host extensive caves (e.g., Omega, Hairy Hole, Rocky Hollow, and Gap Caves) and complex karst hydrogeologic systems. On the limbs of the Powell Valley Anticline, strata dip moderately to steeply into the mountainside, with passage development and flow dominantly along the strike toward water gaps, nickpoints, or structures such as fold axes or faults. Most significant cave development is in the Greenbrier Limestone, which is underlain by Price-Maccrady Formation siliciclastics and overlain by shales, siltstones, and minor limestones of the Bluefield Formation (including the approximately 13-m Little Lime, approximately 100 m above the Greenbrier Limestone). The South Fork of the Powell River, flowing northwest through PowellMountain at Crackers Neck water gap, defines local base level in the area of recent hydrogeologic studies. Dye traces northeast of Crackers Neck revealed that allogenic recharge sinks into the Little Lime limestone layer and flows southwest beneath the river, resurging on the southwestern bank at the Little Lime Spring. High-flow conditions overwhelm the input capacity of the Little Lime outcrops, and water continues down-slope to sink in the Greenbrier Limestone, then flows southwest along the strike through dominantly vadose cave passages in Omega Cave to the Omega Spring on the northeast side of the Powell River. The stream in Omega Cave is undersized, suggesting that most passage enlargement occurs during high-flow events. Inflows in the upper Greenbrier Limestone near the Crackers Neck water gap drain to a spring on the opposite side of the Powell River. Northeast of the Omega basin, flow is to the northwest, resurging at the nose of the Powell Valley anticline. Springs on the southwest bank of the Powell River receive flow from karstic drainage to both the northeast and southwest, as well as from the river itself. At Powell River Spring, river water includes upstream discharge from Little Lime Spring. This situation resulted in confusing dye- recovery patterns before Little Lime Spring was discovered.
