March 26, 2011 #124 - Walking the Lunar Surface Again

Last night I was walking around on the lunar surface again. I was having fun looking at the LROC Zoom NAC M113168034R to locate the natural lunar bridge formed by a collapsed lava tube, which left an unbroken span still in place. This formed a bridge over what was once a flowing river of melted lunar crust. In the search through the zoom for the feature I noticed something interesting in a crater near the photos top. Attached are some screen captures. One showing the overall location, so that the crater can be found. I marked on a second copy the point of interest, and the third a 200% enlargement. The curved shadow is what caught my eye as it seems to point to an above surface projection extending from an apparent square shaped base. I understand that to the untrained eye things are not always what they seem, but it is fun to find this in the data. Take a lunar stroll and look for yourself! Hope you have some fun with this and let me know what you think.
