The Upper Devonian Bluff Point Siltstone in the Keuka Lake area of New York State has depositional structure orientations which suggest paleocurrent directions towards the west-northwest. The rocks are characteristically siltstones and shales with cross-laminae and convoluted bedding structures which apparently formed during deposition. Convolution axes and dip directions of cross-laminae show almost parallel orientation. The unit lacks the characteristics of a turbidite.
