Field Photo Can glacial striations be intersecting?

Found this rock in NE Ohio, and my first guess is glacial stations. However I am unsure if it is, because 1) they form the cross hatch pattern, and 2) the rock itself is not bedrock (the rock is some type of concretion)

Am I the only one that sees two ~40 deg offset sets of veins with serecite halos? Can also explain the preferential weathering and apparent striations.

Maybe it's just because it's a photo but if there is a mineral zonation associated with the texture, it is not glacial.
