North Ray (crater)

The astronauts John Young and Charles Duke explored the area between the craters over the course of three EVAs using a Lunar Roving Vehicle, or rover.

On the way, they drove along the rim of the similar sized but older crater Palmetto, which is approximately 3 km south of North Ray.

A huge (10 m high x 20 m long) boulder, known as House Rock, lies near the southeastern rim.

Based on sample 67955,[5] a noritic anorthosite collected from Outhouse Rock, the impact that created North Ray crater was about 50 million year ago.

This is based on the measured duration of the rock's exposure to cosmic rays.
