Perpendicular stylolite sets

Description

In carbonate strata of the Silurian Tonoloway Formation exposed on Corridor H, near Baker, West Virginia, there are two mutually-orthogonal sets of stylolites: one that is bedding-parallel (due to sedimentary loading) and one that is bedding-perpendicular (due to horizontal tectonic compression). It's a little tricky here, because the strata are now subvertical, so the compressional stylolites (originally vertical) are now rotated to a horizontal position!
