Thunderhead Falls is a waterfall in Pennington County, South Dakota. Height has not been officially recorded. Access details and conditions have not yet been verified in person by Fallspots — the data on this page comes from OpenStreetMap and USGS GNIS.

Thunderhead Falls sits in Pennington County, South Dakota. The base sits at roughly 4,110 feet of elevation. Drive time is about 3 minutes from Johnson Siding. No mapped trail runs within 200 meters — expect bushwhacking or off-trail navigation to reach the lip. No public parking is recorded within 2 km, so a longer approach is likely. It draws modest visitor attention — busier weekends, quiet weekdays. Source records come from OpenStreetMap and USGS GNIS.

Is the water flowing right now?

Most waterfall sites don't tell you this. The waterfall itself is almost never gauged, but a USGS streamgage in the same watershed can tell you whether snowmelt has started, peaked, or run dry.
