The Yeehaw Junction plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Yeehaw Junction’s center stands about 70 ft above sea level. Within three miles the land runs from 50 ft to 100 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Undifferentiated sediments (sand, clay), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 14 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Sand, limestone. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 2 mi of the line.

A raindrop that lands in Yeehaw Junction reaches the St. Johns River and the Atlantic Ocean by way of Blue Cypress Creek, Blue Creek and Trout Creek: about 310 river miles.
Lakes on the way: George, Lake, Monroe, Lake, Blue Cypress Lake and Washington, Lake.
100 miles of the trip are on Trout Creek.
