Hello, Mark,
First, I want to thank you for your time and great work on these images and the flyovers. You did a great job on the Blair Cuspids decades ago with the VGL group, and now we have FOUR LRO images to study some day on those "spires", but right now the "structures" in the LRO images are much more compelling.

I just wanted to pass on some thoughts as early as possible regarding the mysterious "towers" and "structures" we've been playing with the last few weeks. They have been circulated on the internet/YouTube for a while but nobody did anything with them. Ananda Sirisena brought them to our attention in mid-May and the Lunascan Project went to work to confirm their existence and to study what they are. I discovered the "towers" on the Apollo 15 image last Friday, AS15-P-8868. The next day Ananda found them also on AS15-P-8873. We had originally the M118769870L frame from early June that started all this and then we found three other LRO images of the "structures" or tubular objects, making a total so far I think of six images. At the outset you and I were convinced that the "structures" were not "towers", and all this time we had been looking for alleged "towers" near the "structures" but possibly as far apart as 85 km. It turns out that they are all one and the same, with the Apollo 15 res being considerably less in 1971 than the LRO which in 2010 and 2014 was much higher. We are certainly glad that we have confirmed the targets on 6 images and that we now know that whatever they are, they existed in 1971 and didn't "arrive" later.

Brad Sparks calculated from the LRO support data that a degree of selenographic longitude is 28 km at the 21.64 degs latitude and the strip image is supposed to be 0.09 deg longitude wide hence about 2,500 meters wide.  Measuring with his ruler, the longest object image is about 2.3% of the 2500 m width or about 60 meters (200 ft) long.  The smaller one is 2/3 of the longer one, or about 40 meters (130 ft) long. The craters are almost half filled with shadow so he was guessing that the sun's elevation angle was maybe about 20 degs so the approximately 40-meter long shadow cast by the upper (smaller) object would correspond to an object height of roughly one-third or say 15 meters or so.  The longer object is casting less of a shadow, about 30 m long so it would be about 10 m high. I thought that support listed the sun angle, but I didn't see it, so we may have to recalculate.

I think that by going with the best LRO image we can conclude that the objects are actually tubular structures and very large. There is evidence all over the place in the image blow-up of non-natural features. I think the "ramp" of lunar regolith below the lower "tube" is evident of a reinforcement, and can even be seen in a smaller section below the top object as well. And the meteorite impact to the left of the "ramp" suggests the "bulldozed" area was marred marred later, and that these features are VERY old. There even appears to be damage sustained on the right side of the upper object. And the right-angled wall to the left of the main structure is very interesting, indeed. If that's not enough to get some attention, the area where all this sits is a very shallow bowl-like depression, unlike any lunar feature I've ever seen. It's not a crater and it's not a "ghost crater". It looks like an area that has been "worked". The "structures" are within it, dead center. Fresher (bright) impacts can be seen to the SE which is really NW (N is at the bottom) since the orbiter was moving N-S on that low pass.

Some additional notes about the top structure:

I get the impression that it is an inclined entrance to an underground base or other facility. The rectangular area attached to or adjacent to the top of the upper object is an optical illusion. It casts no shadow, however the object itself does cast a large telling shadow. There is a crater in this rectangle that clearly points to a flat surface and not a part of the actual structure.

The first thing that entered my mind when I saw this image was that these were expended rocket stages or a fuel tank jettisoned by the U.S. or Russia or China. But all the big boosters are expended close to Earth and this leaves only smaller rockets for orbiting and de-orbiting. And even more important than that, there are no indications of an impact of any kind. In fact, the "ramps" indicate fortifications, and they are even compromised by meteorite impacts. I feel that we are looking at evidence supporting what Carl Sagan had suggested many years ago, ancient artifacts.Now before anybody jumps to conclusions, there are several possibilities, and ET is only one of those. We don't know the answer, yet..

I also feel that we need to discuss this all out as much as possible, covering all bases, before we make any official announcements. And then only with signatures of support.

I have several NASA contacts but I would rather give them our final formal report than tell them what we are doing now. I don't want to see any of these images go down on the NASA sites. I thought about James Oberg and whether he should be brought in, but I'm not sure, even though this is not a UFO issue, if that would be a good idea. One thing for sure, it makes the point that we may not be alone.

We need to sit back and take a hard look at this and get all the support/signatures we can get, along with comments we can quote. If all works out as planned this will be an interesting find that we can all agree on. What happens next is anybody's guess, but it's something that just had to happen. I just wish Carl Sagan were here to comment.

A little information on the res we are dealing with here, as compared to some of the poor images of the past and lunar researchers.
LRO
The best-available evidence would be images from the 100,000+ frames of the Lunar Reconnaissance Orbiter taken circa 2010. These are the highest resolution to date and range in quality all the way up to 0.5 m/pixel.

APOLLO METRIC & PANORAMIC CAMERAS
The Metric Camera (mapping camera) obtained pictures of the surface covering 165 kilometers on a side, with a horizontal resolution of 20 meters, based on a nominal spacecraft altitude of 110 kilometers. The Panoramic Camera obtained pictures of narrow strips, 20 kilometers wide in the direction of spacecraft motion and 320 kilometers long across the spacecraft's ground track. These pictures had extremely high resolution, showing features just 1 to 2 meters across. Photographs with both cameras were taken so that there was substantial overlap in the ground coverage of consecutive photos. This allowed the technique of stereo photography to be used to determine the heights of features shown in the photos. Under ideal conditions, the heights of these features could be determined to an accuracy of better than 10 meters. The results of this stereo photography were used in producing topographic maps.
