Goose Creek Lake’s center stands about 770 ft above sea level. Within three miles the land runs from 610 ft to 1,080 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Wiggins Hill, about 1,170 ft, 11 miles south-southwest.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Cambrian, 487 to 497 million years old. About 7 mi of the line.
Dolostone, shale, siltstone. Age: Cambrian, 487 to 497 million years old. About 7 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 4 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Dolostone, limestone, shale. Age: Middle Ordovician, 459 to 471 million years old. About 1 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Goose Creek Lake reaches the Gulf of America by way of Goose Creek, the Fourche a Du Clos, Establishment Creek and the Mississippi: about 1,120 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Goose Creek Lake; river miles along the main stem, rounded.
