Abstract

Tycho (52 miles) is one of the youngest large craters on the Moon. Its walls are heavily terraced and rise upwards of 2¾ miles above the floor. There is a large central mountain mass that reaches up to about 1 mile from its base. Around the floor there are small hills scattered here and there. While Tycho is located in an area of heavy cratering it is so prominent that it is easy to spot 1 day after first quarter. This beautiful crater is another must show formation at any public observation.

Street (35 miles) is a fairly shallow crater that is less than 1 mile deep. There is some terracing of its walls that surround a flat floor. I see little detail on the floor, even in my 6 inch refractor.
