Airborne is a Class IV- rapid located at mile 5. 2 on the Tuolumne River below Lumsden, featuring an innocent-looking series of drops leading into a steep falls with rocks plugging the exit.

The best route follows a Z-shaped path on the left side, and paddlers should scout right to avoid a large rock wall on the left that has historically jammed rafters' oars.

Clavey Falls, one of the river's most challenging rapids, follows almost immediately downstream.
