32.2 Granule-bearing quartz arenite. Clinch Mountain, Broadford Quadrangle, Virginia.  Medium-coarse quartz sand in this view contains some granules of quartz (e.g., in the center of the photo) and is cemented locally by yellow-brown limonite and pink to red hematite.  Greenish –gray patches are lichens growing on the rock. [Scale is standard GSA scale with cm divisions.]
