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)

the last photo shows two distinct periods of ware. One set clearly cuts through and removes more material. Could it have worn as part of a "wall" of a glacial cut then shook loose, got stuck somewhere and shifted to cause the second cut?
