LiDAR & 3D terrainAbout Flatrock Falls
Flatrock Falls is a quietly scenic cascade near Petros, Tennessee, tucked into the Frozen Head land unit (designation: SP) and managed by OTHS. The falls are set among lush forest and rocky outcrops, making it a peaceful, lesser-known stop for hikers who prefer solitude and unspoiled scenery. Visitors will find a natural, undeveloped setting that rewards those willing to hike in for quieter views and photography. Access to Flatrock Falls tends to be low-key compared with busier regional attractions. The nearest maintained campground is Rock Creek Campground, about 22.12 km away, so plan your trip and supplies accordingly; bringing water, a map, and sturdy footwear is recommended when visiting the Frozen Head land unit.
The Setting
Flatrock Falls sits at 1,667 feet within Frozen Head, in the hills of Tennessee.

How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.

Winter safety. Frozen falls are the one waterfall trip with a documented injury pattern: falling ice, and ice-glazed rock and trail. Wear microspikes, keep well back from the base and from overhangs, and never walk out on ice over moving water.

The Terrain, Seen by LiDAR
Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.
1-meter lidar shows the creek losing roughly 117 feet through Flatrock Falls over a long run of ledges. Elevation at the pin is about 1,672 feet.
The whole reach is steep: about 100 feet of descent in the 500 feet above the falls and another 76 feet in the 500 feet below. The falls face northeast and stay mostly shaded, with soft, even light all day.
