A Low Ragged Front

Another view, or views, of yesterday's Apennines. Tom has taken his own image (right) and using LTVT draped it over LRO digital elevation data to produce multiple views from different directions. The shadows are from Tom's original image as "cast shadows" was disabled for the 3D rendering. He didn't say, but it appears that there is no vertical exaggeration. In the bottom left view, looking from Mare Imbrium eastward, the Apennines look like a low, nearly continuous wall, rather than the towering scarp we often imagine from low Sun images with shadow spires. Nearly all lunar topography is less spectacular than it appears in a low Sun telescopic view.
