This is the original image from a North American Lunar atlas that caught Hoagland's eye. Taken from the ground based Lick observatory, the crater Ukert is virtually dead center in the Lunar disk from an Earthbound perspective, and it's dark floor is a nearly perfect 16 mile equilateral triangle at full Moon. Imagery from the Clementine Lunar Image Browser ......

..... And raw Clementine low res UV-VIS images ....

.... confirm the basic triangular shape of this crater. It should be noted that Ukert is not a natural looking feature in any way, and it is difficult to imagine how it could have achieved this shape due to a meteoric impact. Even an "impact-collapse" scenario would not likely create a triangular configuration. High res images from Clementine would help resolve issues of artificiality, but the matching hi-res pictures are mysteriously blacked out on the various Clem file servers. This is a common occurrence concerning features of interest to this investigation.
