Nobody's Fault But Lee Lincoln Moon Scarp

The Lee Lincoln Scarp shows a fault at the Apollo 17 landing site



Hey people, let's do some Moon Herald Travelling! In 2010, planetary geoscientist Thomas Waters and others at the Smithsonian Institutions’  National Air and Space Museum looked at evidence from the NASA Lunar Reconnaissance Orbiter that seemed to suggest visible faults on the surface of the moon were not so ancient - that they were as young as 50 million years old. Waters recently led a study which conjectures that there was much more seismic activity on the Moon then was previously thought. This leads to the tentative conclusion that the Moon is actually somewhat tectonicaly active.

Viewed from afar one such young fault looks like a river - get closer it looks like a scar. It is a thrust fault traversing Lee Lincoln Scarp (a ravine named as some ode to Civil War equivalency?) where Apollo 17 set down.

The author of a NYTimes reports writes:  ''The moon’s thrust faults are a sign that the whole orb is contracting as it loses internal heat, cools and shrinks; Mercury is undergoing a similar process.''
