Mystery rocks? Alien footprints? Pardon me, but it looks like plain old breccia to me. See:
_http://geology.about.com/od/rocks/ig/sedrockindex/rocpicbreccia.htm_ (http://geology.about.com/od/rocks/ig/sedrockindex/rocpicbreccia.htm) Louise No question about it being breccia, I just want to know how it happened. How could such a cake mix slurry of broken chunks get embedded in conventional limestone then get spread in a thin flat layer across a wide area? The relative hardness could well be an unrelated issue. Sleazel
