Lunar Features - channels, cooling cracks, pits, domes

Er, channel, chain ...?

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.

These are quiet possibly skylights for lava tubes under the surface

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.
