Siltstone

 · Resistance to weathering —Shale, siltstone, and mudstone units are valley formers, producing gentle slopes and subdued landforms, including broad "V"-shaped gullies having long, gentle stream gradients. Drainage—Shale, siltstone, and mudstone units have relatively low permeability, resulting in significant surface flow. This produces a high drainage density.
