That same sort of breccia is on the CWAN property. I doubt that it's the KT boundry but it is a mystery. If any of you geologists want a sample I'll show you where it is. I'm pretty sure it's in the upper part of the Lower Glenrose formation.

Alien footprints? Pardon me, but it looks like plain old breccia to me. See: 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 ------------------------------------------------------------------------------ No virus found in this incoming message.
