Lee is the lava

Lava

Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...

Moon

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Impact crater

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Mare Humorum

Mare Humorum is a lunar mare. The impact basin it is located in is 825 kilometers across. It was not sampled by the Apollo program, so a precise age has not been determined. However, geological mapping indicates that it is intermediate in age between the Imbrium and Nectaris Basins, suggesting an...

. To the east is the crater Vitello

Vitello (crater)

Vitello is a lunar crater that lies along the southern edge of the small Mare Humorum, in the southwest part of the Moon's near side. It lies just to the east of the lava-flooded crater Lee. To the northeast along the edge of the lunar mare is the Rupes Kelvin, an irregular fault line.This crater...

Doppelmayer (crater)

Doppelmayer is the remains of a lunar crater that lies on the southwest edge of Mare Humorum. To the south-southeast is another flooded crater designated Lee, and to the southeast is Vitello. Just to the east-northeast of Doppelmayer lies the nearly submerged crater Puiseux.The rim of Doppelmayer...

.

The rim of Lee is worn and somewhat eroded, with a wide gap along the northeast where lava entered and covered the floor. The interior is relatively flat and free of significant impacts. The craterlet Lee A is attached to the exterior of the southern rim of Lee.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Lee.
