The strata are probably Devonian in age, redbeds deposited by streams draining the newly-upthrust Acadian highlands to the east, and then carrying the resulting sediment to the west towards an epeiric sea. Maybe they’re the Hampshire Formation; That’s what they look like at first glance. The flute casts are on the bottom of a sandstone bed that was deposited atop a red shale bed (into which the flutes were scoured). Stratigraphically, you’re looking “up” at the bottom of that bed, although its modern position (thanks to the subsequent Alleghanian Orogeny) is vertical, so really you’re looking sideways.
I held the quarter to the vertical bed with a wad of chewing gum, by the way.
