Surely it has to be a whole series of photos, in order to have so many different views, at any angle you like and at varying altitudes from about 3,000 metres or lower, doesn't it?
No it doesn't, it could be on one image which you zoom in on. Since there is not change in image texture as you zoom in I suspect this is the case.
The pictures have "NASA" "Selene" "ASU" etc stamped on them.]

Actually no. the particular feature is in an image (or set) that says NASA/ASU.
Ok my mistake - NASA and ASU are the same. Selene is an orbiter owned by the Japanese though.
NASA and ASU are not the same. ASU is Arizona Sate University, which has a strong planetary program. Some Google Moon images are from SELENE (Kaguya), some are from NASA.

Who says it is a fake? There are plenty of ways erroneous features can be generated without deliberate fakery.
I agree. But this object isn't like a data drop-out glitch, or bits of black that appear in some places on the lunar surface, or terrain that gets repeated like a wallpaper pattern in some places in Google Earth or Moon. It's a single, large object with a definite shape to it so I'm not sure how a simple data glitch could put it there.
There are other ways of generating image defects that don't involve data drop outs. For example there are excellent images of the Moon from the Lunar orbiter program. These were shot on film which was developed on board, scanned, and transmitted back to Earth. Some of these images contain a range of defects, including bubbles, holes, scratches, and small bits of debris. These are all real objects in the images, except they are not on the Moon but in the camera. If these were used for Google Moon they would have been be scanned to convert them to digital imagery. This can introduce further defects through objects on the scanner glass or lens. Again real objects, but not on the Moon. Lunar Orbiter wasn't the only film camera to be used in lunar orbit. The Apollo CSM on almost all missions carried a range of film mapping cameras of varying resolutions.
This is why it is important to know which image this feature is on and its history, and whether it appears in other copies of the image. If it appears in all copies then it is likely to be something in the orginal camera (or even on the Moon), if just on Google Moon then something that was accidentally created in the process they used to create it.
Here's a page that explains how Google Moon works. This is an extract from that page:
We've included four different types of data in Google Moon:
Visible - A mosaic of images taken by the Clementine mission. This is a black-and-white version of what you would see if you were in orbit around the moon. This composite imagery was prepared by the USGS.
Elevation - A lunar terrain map generated by the USGS in conjunction with the The Unified Lunar Control Network 2005, and shaded using an airbrushed shaded relief map. This map is color-coded by altitude, so you can use the color key at the lower left to estimate elevations.
Apollo - A collection of placemarks that tell the story of the Apollo missions that landed on the moon. This includes stories, quotes, images, panoramas, audio clips, and links to videos of the astronauts' adventures on the lunar surface.
Charts - A collection of geological and topographic charts of various regions of the moon ...
The problem is that is inaccurate, or at best incomplete. There is no mention of of the Kaguya imagery, for example.
Every image of the Moon has a unique image number. The same with every image of the Earth, for that matter. I know in Google Earth you can find the specific base images used, I found this out by accident one day and have not been able to get it back. You should be able to do the same on Google Moon. Once you have the image number you can get it from other sources.
I called the Daily Telegraph news desk yesterday and followed up with an e-mail giving the co-ordinates and a link to this thread. The papers have printed stories in the past about anomalies in Google Earth (such as that "Atlantis" thing for example) so maybe they'll be interested in this.
I wish people would not use "anomalies" in this way. An anomaly is simply something that stands out from the background. Unfortunately the woo woo crowd use it to mean "evidence for aliens, grand unified conspiracies, and things of that sort".
The trouble with senduing such stuff to the newspaper is that they will generally either ignore it if there is no story, or sensationalise it.
I also just sent an e-mail to NASA, giving them the Google Moon co-ordinates and a link to this thread as well. I asked them to forward my e-mail to USGS, Google or any other experts as neccessary. Maybe we'll get an answer from somebody soon.
You could also contact Google. That should be the first step, as they created the image you see in the first place. That is what NASA or the USGS would do if they follow up your request. They would need to find out the base image number from Google and proceed from there. Or you could contact the astrogeology program at ASU.
