Er, channel, chain ...? ;D

This picture shows the southern end of the Lee-Lincoln Scarp by the Apollo 17 Landing site.  This southern portion goes over the mare filled Taurus-Littrow Valley.

A rille, possibly sinuous or a cliff on the edge of a large crater


To go along with you and Geoff's images, they are infact images that belong together.  The feature you both are looking at is the northern portion of the Lee-Lincoln fault scarp near the Apollo 17 landing site.  The fault first cuts the basaltic filled Taurus-Littrow in the south, cutting straight north.....then when it hits the North Massif (the lighter area you see in the photo) it takes a sharp left through the highland material.  I'm currently researching these thrust faults and we're finding that they're globally distributed.

Latitude: 23.9343°
Longitude: 312.405°


These are quiet possibly skylights for lava tubes under the surface

I've seen that scarp quite often, found a few more somewhere a while back.

Found these in a crater in Powell, Jules pointed out that they are cooling cracks, which I thought the floor was settling and caused them.

An interesting backwards L shaped pit/crater in the bottom left corner.

Welcome to Moon Zoo Chris.

Your pit/crater looks like two connected craters to me but it's difficult working out exactly what it is with the terrain.

Hi Rocketpower and welcome to Moon Zoo.

This looks like a sinuous rille and is formed by volcanic action (there is very little water on the Moon). Rilles can be formed from lava flows or from the collapse of a lava tube.

It would help if you could post the latitude and longitude of the image so we could research this area.

There is a good article here about rilles.
