Discussion from McGrain and Currens (1978)
The tableland area occupies the largest part of Jefferson
County. To the casual observer, the details of the topography are
obscured by the extensive urban and suburban development. Although locally
appearing flat, it is essentially a gently southwestward sloping surface
from a high of 790 feet on the east to 500 feet at the foot of the knobs
in the southwest part of the county. Floyds Fork and Harrods Creek have
cut valleys as much as 150 to 200 feet below this surface in the east-central
part of the county. Some sinkholes are present, but these karst features
do not constitute an important part of the landscape.
The highest elevations are in the Muldraugh Hill (Highland Rim) area. Here the escarpment rises abruptly 300 to 400 feet above the lowland to the north and east. South Park Hills is a complex of hills and ridges separated by erosion from the main upland to the west. The highest point in South Park Hills, and the highest point in Jefferson County, is 902 feet. Holsclaw Hill, 2 miles to the west, has elevations of 890 feet.
Selected elevations in Louisville are: the courthouse, 462 feet; Churchill Downs, 455 feet; highest elevation in Iroquois Park, 761 feet; terminal building at Standiford Field, 475 feet; main gate at Kentucky Fair and Exposition Center, 480 feet; and University of Louisville campus (South Third Street), 460 feet.
Other elevations in the county include Anchorage, 720 feet; Coral Ridge, 490 feet; Eastwood, 720 feet; Fern Creek, 715 feet; Fisherville, 559 feet; Jeffersontown, 711 feet; Kosmosdale, 449 feet; Middletown, 721 feet; Prospect, 460 feet; and Valley Station, 452 feet.
