Mapping of regolith layer thickness for the lunar nearside is carried out with Arecibo radar data at 70 cm wavelength (T. W. Thompson 1987, Earth Moon Planets 37, 59-70) and distributions of iron and titanium content derived from Earth-based optical data (Yu. Shkuratov et al. 1999, Icarus 137, 222-234). For the mapping a new simple model of radio wave multiple scattering in the regolith layer was used. A comparison of this map with independent estimates of regolith layer thickness for landing sites and other areas of the lunar surface showed a good correlation. It was found that regional variations of thickness are almost the same for maria and highlands, though the average thicknesses are different (5 and 12 m, respectively). A relatively thin regolith layer (4 m) covers a portion of Mare Serenitatis, Mare Tranquillitatis, and Mare Humorum, while the thickest regolith layer occurs in Mare Nectaris (9 m). A thin regolith layer is a characteristic of the cryptomare Schiller-Schickard. Very small regolith thickness corresponds to the crater floors. In this case, the model cannot yield reliable estimates of thickness; it predicts only a characteristic distance between rock inclusions buried in regolith. A thick highland regolith occurs at the southeast portion of the lunar disk and the highland to the north of Mare Imbrium and Sinus Iridium. For the lunar nearside, the regolith thickness generally correlates with the surface age: the greater the age, the thicker the regolith. The results are consistent with a higher rate of regolith growth for times earlier than 3.5 byr ago, when meteorite flux was much higher.
So the regolith is an average of 5 meters thick in the maria and 12 meters thick in the highlands, or call it 16 feet and 39 feet if you prefer.
I suspect what you are referring to is how much of the regolith is compacted versus how much is uncompacted, and you're right that the the regolith a few inches below the surface is compacted, but it's still regolith.

salaam

You got me on that point: skepticwiki.org...
I'll research further to see what the response is.
Two thumbs up for ya.
To their credit, some creationists are abandoning the moondust argument

I'm sorry I misjudged you John Matrix. I thought you were one of those creationists who would stick to their beliefs no matter how great the observational evidence to the contrary. Now that you have demonstrated to me that you actually do consider such overwhelming evidence, even posting a link that says:

then I have to agree with that statement, that it's to your credit that you consider the evidence against that argument!
So two big thumbs up for you too!

Many protists reproduce both sexualy and asexualy, so even your absurd example is not a problem for them, because when they had not yet fully evolved sexual reproduction capable of fully substituting the asexual way, they can use the asexual to reproduce too.
But it gives them some comparative advantage over the mutants with only asexual reproduction.
This is basic biology, for the sake of fsm...

You are comparing the reproduction of higher forms of life to protists(micro-organisms)?
It is your dance around the topic at hand that is absurd.
Evolution is all part of the grand scheme to dumb down the sheeple.
It's working.
How people that can articulate as well as you, Bunken Drum, and a few others and yet believe in such nonsense is nothing short of a miracle.

Yes, I am comparing evolution of reproduction of higher forms to single-celled forms, in a way.
The evolution of multi-cellular genders was similar, with hermaphrodites in the beginning, evolution of two sexual chromozomes, and extinction of heramphrodites due to advantages of two sexes.
There are still open questions on the evolution of sexes, but it is not disproving evolutionary theory.

Hi! The Origins of Man (dvd netflix). The dvd is a three part disc set,
that is facinating and intelligent. They said Darwind's theory could not be backed up. Its missing all the linking skeletons. They are leaning towards Alien DNA expeiments on the primates to produce humans. They discussed the human footprints with the dinasaurs 2-3 million years old, found with a hammer tool in the same strata layer that was an iron cloride compound forged from liquid metal 2-3 million years ago. Humans were
pouring metals into molds and made staple clamps to hold stone blocks together at Tenonacha (SP?). They also emplasized that cataclismic event
caused crust displacement, and glaciers (which were two miles thick) to melt rapidly flooding the oceans 500 feet. These are today's scientists
theories, why does Darwin of the past matter so much? I think that new information is coming all the time that out dates old speculations. We need to remain open to new ideas.

Abiogenesis, Micro-evolution, natural selection, adaptive response etc. is not evidence for evolution, nor does it stand as proof of evolution.
Micro-evolution can just as easily be explained as the result of a creator using an intelligent design application that He instilled into our genetic makeup.
I'm not saying you are flat out wrong. I'm just saying that the creation view is more reasonable, taking into account the enormous odds against life coming from non-life particles, and the tremendous amount of information contained in DNA within each cell.
I don't believe speciation is evidence for macro-evolution. I have no doubt that variation within groups of organisms proves they adapt to their environments, but these adaptive changes are not without limitation.
Micro-evolution does not prove macro-evolution. Micro-evolution is more logically explained as a genetic instruction being carried out in response to the environment. I believe that DNA contains the design application which contains the adaptive response instructions. In my mind, an intelligent source is behind the application/program/instructions contained within the DNA of each cell in each creature.
In addition to what I have stated above, I brought up the difficulties with "sexes" because it makes evolution that much more difficult to accept.
