Here's another photo of an unconformity you can put your finger on. This one is from the front ranges of the Canadian Rockies. It is a contact between Cambrian and Devonian sediments. On the left, the light grey/buff rocks are Cambrian. This unit is brecciated and trilobite fragments have been found in it. On the right are Devonian rocks. This unit contains stromatoporoids.
Hi Tannis, I found myself here from All-geo, and wanted to say, after perusing around, that you have some very nice geologically eclectic blog posts. The upstate NY posts are great especially for an upstater-educated geologist like myself (long ago). I think your letter to an undergraduate is just as good advice for a geology student today as it would have been in my day. Good luck with your research and career.
