The rocks down along the river fascinate me...

They have these lines of quartz layers that run in all different directions, many intersecting each other. I'd love to know more about how these are formed.

Almost looks man made. Rarely are lines that straight in nature. Very cool pic KB!

Lots of the stuff in Northern Ontario, I agree very cool.

It looks like previous global warming evidence to me. :^)

The rocks crack. Water flows through the cracks (undergound) carrying dissolved minerals, which are redeposited in the cracks. Later, the rocks are exposed through erosion, earthquakes, etc.

The geologist who worked at the little oil company I once worked at says that the Appalachian and eastern mountain range was once 30,000 feet tall and had weather, geologic activity, and erosion we don't see anywhere in the U.S. now.

That makes perfect sense, thanks!
