Oceanus Procellarum
9.40° N, 61.70° W
One of the largest unclaimed craters on the near side, wide enough to swallow a city and deep enough to hide a mountain.
A four-inch telescope from Cottonwood Spring resolves the rim shadow cleanly on a steady night.
Large craters that catch the sunrise line and throw kilometres of shadow.

The Moon keeps one face turned toward Earth, so your crater is fixed in the same spot of sky every clear night of your life.
JTC-1402 lies at 9.40° N, 61.70° W, in Oceanus Procellarum. On the map, north is up and east is to the right, exactly as it appears through a telescope from the high desert.

Adrift in the Ocean of Storms, the largest dark expanse on the Moon and the last ground the lunar sunset reaches each month.
Mare Tranquillitatis
Less than 200 kilometres from Tranquility Base, where Apollo 11 set down in July 1969. The same dark basalt that took the first human footprint.
Sinus Aestuum
In the Bay of Billows, sitting on one of the darkest deposits on the Moon: volcanic glass beads sprayed from ancient fire fountains.
