Hitchhiker's Guide to Rukl Chart 11

Moon Sheep (JRF <freeman _at_ netcom.com>)

Bay Area observer <NEUSCHAEFER_RICH _at_ Tandem.COM> Rich Neuschaefer thinks that the isolated, hummocky hills and mountains of the northern Mare Imbrium resemble a flock of sheep grazing on a bucolic pasture. The mountainous merinos include the Teneriffe Mountains (Montes Teneriffe), the Straight Range (Montes Recti), the Spitzbergen Mountains (Montes Spitzbergensis), and the isolated peaks Pico, Pico Beta, and Piton. The Spitzbergen Mountains and Piton are on Rukl chart 12. I have always had trouble remembering which is which among Pico and Piton. Possibly it will help to note that Pico and Plato both end in an "o", and that Pico is closer to Plato, than Piton is.

Robin Casady's CCD image of Plato, at left, shows the Montes Teneriffe and Pico (the image is linked to a larger image with the major features labelled).

See also Thierry Legault's CCD image of Piton on chart 3.

Wrinkle Ridges (JRF <freeman _at_ netcom.com>)

The eastern Mare Imbrium has wrinkle ridges extending south from the vicinity of the Teneriffe Mountains, and west southwest from the Spitzbergen mountains.
