Astronauts David Scott and James Irwin visited the east rim of it in 1971, on the Apollo 15 mission, during EVA 1.
Geology Station 2 was to the southwest of the crater, up the slope of Mons Hadley Delta.
Elbow is approximately 0.5 km north of the foot of the Hadley Delta slope.
The surface material is composed of fine-grained soil with sparse to common pebble-size and larger fragments.
