Howard >> Some of these blocks happen to be buried under a thin layer of till (gravel), which begins to slump off on all sides of the ice block. The block eventually melts completely, leaving an empty pit, surrounded by a ring of gravel. I don't blame you if you're not totally convinced by this explanation <G>. << a little thin but Not bad…. the infant donut pools water in its center and freezes and thaws and slowly pushes the stones outward while ponding in the areas between donuts corals them inward. The expanding ice moves the stone and then releases it on thawing. Your description of the glacial morains is much as I anticipated. Most all gravel beds do not include the rough stones that are obviously part of a grinding process. When looking at landscapes I try to also invision a rapid creation cycle of the basic components of the area…that is a cataclysmic catastrophy senario where a uniform flat landscaped earth was hit by a huge meteor or anouther favorite a Stellar flyby that ripped off the missing continental mass and jumbled the remaing continetal crust into the distended tumbled domino mountains and ripped apart fractures…the canyons and river valleys ect. The KT boundrey marks when it occurred. When reviewing both processes the rapid event wins most likely to me. I love the planet earth and the story of how it all came about is carved into her, there is more than one good answer to most geological histories.
