Like breaking waves that sometimes indicate reefs lying just under the surface of the water, wrinkle ridges often signal the presence of subsurface structures on the Moon. Serpentine Ridge reveals the ghostly outlines of an underlying mountain range that formed the inner ring of the Serenity basin. At the highest point of this ridge, just west of Posidonius where it looks like the ridge splits into a “Y,” there is a tiny 1.2-mi. crater that will test both your optics and the seeing conditions.

It is available for $10.95 at www.skyandtelescope.com and on Amazon. All features mentioned in this blog will be keyed to the grid on the Field Map and will look like this: Plato: [NW/D9]
