Ho hum, Map-A-Planet). The upper part of the chain, near shore, is definitely a secondary crater chain cluster. But the bottom part doesn’t show as chain on the Orbiter image, in fact there is hardly anything there at all at that magnification. But blow up the Orbiter image and there is a very narrow sinuous rille! It starts near the eastern side of the Prom. Laplace, wanders pass the isolated peak, crosses the mare ridge, and abruptly turns south and disappears. Comparison to the nearby 11 km wide Laplace D crater shows that this sinuous rille is about 500 m wide. Not bad for a 10″ Mak in Buffalo! More about the rille tomorrow.
