Day one of my stratigraphy trip: Cove Palisades Park

Day one of my strat trip found us mapping fluvial and volcanoclastic deposits in the Cove Palisades State Park. It was nearly four hours of hiking up the road, examining the road cut, and taking measurements. What did we find? Lots of fluvial deposits such as rounded cobbles and sand stone towards the lake and volcanic teffra towards the top. Here’s a few pictures to show the sequence. I included scale where it was safe to do so. I can’t get into too much detail because I’m posting this from my phone.

Layer of cross-bedded sandstone on the bottom with rounded cobble on the top. All indicative of fluvial deposition.

The meeting of fire and water. The rounded cobbles at the bottom were deposited in a fluvial environment. The thick layer in the middle is from an ash flow, while the layer directly above it is ash fall. The later directly above that is more rounded cobble.

And to end it all, nice columnar basalts.
