Up and Down the Marius Hills
An even wider view places the feature north west of Marius R crater in an area where the outer rays from Aristarchus, Kepler and several craters to the west overlap on the eastern edge of the Marius hills. This particularly rugged terrain is also marked by lava flows, sinuous rilles and mare ridges. About half of the Moon’s volcanic domes are in this region. Lunar domes are much smaller than shield volcanoes on Earth. The Marius hills range from 200-500m in height whereas the Mauna Loa volcano in Hawaii (the largest shield volcano on Earth) is 17,170m tall. Here is a wide field image with the featured region indicated showing its proximity to the Marius domes:

Photographed from a more oblique angle by the LRO’s Wide Angle Camera the domes are more impressive:
So what is going on in kodemunkey’s image? Rotating the image so that north is up and using the topography graph from the ACT-REACT Quick Map shows a steep drop from west to east. Lava flows appear to have created a complex knot of ridges and valleys. The pale tracks at top left are very bouldery and connect to 2 small craters suggesting that they are more recent landslides and flow from higher ground towards the lower rugged region.
Kodemunkey found his image from the latest LRO data release 11.
