I don't think anyone has ever anticipated finding glaciers of white ice just sitting in the bottoms of polar lunar craters. Exposed ice would sublimate quite quickly when exposed to the vacuum.
Instead, I believe the expectation is to find an "icy regolith" layer (something like a permafrost layer) underneath a completely dry layer of regolith. The minute gaps between the grains of the covering regolith cap would be enough for the tiny amount of sublimation that results in the hydrogen signature detected by Clementine and Lunar Prospector. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
