Went up Marble Mountain Route then over towards Monitor Ridge @ Chocolate Falls. Skied an outcropping just below Monitor Ridge, SW/S/SE aspect, from 5200' to 4600'. Fairly wind protected, not many features of note. May have noticed some whumphs with skin steps around 4600' or so, possibly a layer ~5" down? Mainly in the flatter areas, didn't see any crack propagation. Did not notice as I ascended. Once sun hit these faces rollers appeared pretty quickly at a few spots higher up and rolled down. Stuck to 25-30 degree slopes, nice snow for some turns.
