Stacked ridgelines traced from real elevation data across a 20-mile square around downtown Knoxville, with the city's coordinates set underneath. The ridges and valleys of East Tennessee, drawn as clean lines. One-color print that works on any shirt.
This one is real data. We took elevation data for a 20 x 20 mile square centered on downtown Knoxville, sliced it into west-to-east profiles, and stacked them from north to south. Every bump on every line is actual terrain, smoothed a little so the lines print clean.
Inside the square, the ground runs from about 812 feet to about 1,698 feet, roughly 900 feet of relief. The rises trace ridges like Bays Mountain, Sharp's Ridge and House Mountain, with the Tennessee River, Holston River and French Broad River cutting through the lower ground.


Yes. Each line is a real west-to-east elevation profile across a 20 x 20 mile square centered on downtown Knoxville. The map on this page shows the exact area.
Ridges like House Mountain and Bays Mountain rise above the valley floor, while the Tennessee River and its tributaries carve the lower, flatter stretches.
