This sounds to me to describe a very common and normal geological phenomena called "loading". When a silty sediment is permiated with water, it becomes very soft. When the tension at the surface is broken, objects from the surface (e.g. pebbles) sink down untill it hits a sediment layer where the tension is strong enough to stop it. The results is that you see, in cross-section, a channel (that immediately is filled in again - and the layered patterning resulting is quite what you decsribe) with an object at the bottom. It is a very well known and understood geological phenomena, and I've observed it in archaeological trench sections, both with natural objects and artifacts. In some cases it need not even be a solid object, mudd-balls will do as well. So I think there is no need to regard this as a fossil meteorite channel unless the character of the object at the bottom of the channel was clearly meteoritic. - Marco ---------- Marco Langbroek [EMAIL PROTECTED] [EMAIL PROTECTED] http://home.wanadoo.nl/marco.langbroek "What seest thou else In the dark backward and abysm of time?"
