Rille From Ridge
image by " rel="nofollow Christian Viladrich, France
This isn't a spacecraft image, but it looks like one. Christian has produced a magnificent view of the area from Gambart east to Schröter (near bottom
right). Hummocky mounds of Imbrium ejecta provide most relief, with mare lavas from Sinus Aestuum filling in low spots. Radial and looping chains of
secondary craters from Copernicus (beyond the upper left margin) demonstrate that we really don't understand the details of ejecta ballistics. Although
there are interesting rilles along the northeast edge of this frame, what is remarkable is a faint sinuous rille that starts at the mare ridge northeast of
Gambart and flows at least 50 km to the south before becoming undetectable. This rille is barely visible in a Lunar Orbiter IV " rel="nofollow image and may be
generally unknown. For a rille to start at a mare ridge shows that either there may be a volcanic component to some ridges and/or that the low angle
fault of the ridge provided a conduit for magma to rise and erupt on the surface. I am unaware of any other rille starting at a mare ridge.
