Hey Athlon , check out these photographs .

What is the angle of the sun because if its 22.5 degrees thats quite a tall object.
Anaxagoras A at Sunrise
Last Tuesday, LRO's orbit was just above the lunar terminator (the day/night boundary), so huge shadows highlight topography and render many relatively normal areas of the Moon nearly unrecognizable.
I included a picture of towers for a visual reference.
You also are assuming the ground is flat.
As I said before, there is no way to accurately calculate the actual height of the pile of rocks without accurately knowing both the elevation of the Sun and the slope of the ground.
The picture was taken at sunrise. The Sun is not at 22.5º
The details provide in the link are sun elevation is at 11° sunrise at Anaxagoras
Numerically, the colongitude is equal to the longitude at which the "morning terminator" (the theoretical line of sunrise on the Moon) crosses the Moon's equator measured west from the Moon's central meridian (the line of zero longitude) on a scale of 0 to 360°.the-moon.wikispaces.com...
No they don't. Use your brain. What does "sunrise" mean? Sunrise is when the Sun comes over the horizon. You know, like when you watch the sunrise and the Sun comes over the horizon?
For exampe, You have been wrong about the direction of the Shard shadow. I have collaborating proof that i was correct for the direction of the sun is illuminating in the shard picture.No, you don't. Unless you can explain what was illuminating the "shard" from the south instead of the east where the Sun was.
Because we know the actual sun angle at the Apollo 11 landing site, this allows for verifying the calculation. Then use the calculation at the lat/long coordinations of where the anomally sits.
I went looking for more information about it (I know that they usually have the position of the Sun as one of the parameters of the photo), and this is what I could find about photo "nacl00000141".
Note the "incident angle" in the description of the image. That is the direction of the sunlight relative to the surface and the spacecraft. It is 80º. That is from the upper right of the unrotated image. It is not consistent with the "shadow".
You said that the elevation of the sun at sunrise at Anaxagoras was 11º above the horizon. Don't you understand that makes no sense?
That's great, but all the illumination information is already provided for the Lunar Orbiter image. It is also obvious. There is no need to refer to the LROC image and make further calculations but go ahead. But please be sure to take in consideration the latitude and longitude as well as the time of the lunar day at which the images were taken.
No you were wrong about the direction of incident light from sun. Its not coming from the upper right of shard image. This is your quote to a poster on page 20.Yes, I corrected myself when my error was pointed out to me. The proper datum to use was the azimuth, 91º. The light is coming from the right.
Its up to readers now to decide who arguments yours or mine are correct on the shadow.True. But it's also up to you to explain how the "shard" could be illuminated from the south.
Everthing is obvious to people who are only right best half the time.I could argue with your statistics but even 50% is better than seldom.

The moon mappers as i explained in a couple of posts above for explanations for lighting directoon on moon supports my argument where light is coming from left of the picture.You explained nothing when you were talking about that. You verified nothing and the data for the Lunar Orbiter image says the lighting was from the right as do the craters.
Yes i guess it will come down to me as i can see your shadow data hasnt been very convincing.I'm all ears. How was the "shard" illuminated from the south. What was the source of illumination?

The lighting and location details are speculative that ways we are discussing them in this thread.
