Glancing At Ryder

Following up on a link to crater Ryder in a previous 2009 Dec 26, LPOD by given by Chuck in yesterdays discussion post, I had a look to see what high-resolution LRO Narrow Angle Camera images had been taken of the farside crater Ryder (44.5S, 143.2E), and I came across this amazing oblique shot across the crater. Piecing together the two images (insert) of the upper and lower parts of the crater, here is a much reduced sized image showing the scallop block on the floor and crater free rim on the Southeast side. There are other overhead (nadir) views also, including one " rel="nofollow M167268729RE which show the floor at the base of the wall of where a boulder has rolled down. There is another "groovy" image of the scallop in this image " rel="nofollow M113012783L which is visible in the Kaguya image in the previous LPOD. " rel="nofollow Graham Ryder was a great lunar geologist, and he certainly has a very interesting crater named after him! I hope you enjoy exploring it as much as I have.

The " rel="nofollow LROC WMS Image Map was used to find the images based on the lat/long of Ryder given in the 2005 Feb 16, " rel="nofollow LPOD
The image above has been mirror reversed to hopefully correct for the NAC mirroring.
