PLATE 17 HYPOGENIC MORPHOLOGY OF COFFEE CAVE<br />

Plate 17. Hypogenic morphology in Coffee Cave, NM, USA (Permian gypsum): Feeder features (photos and compilation by K.Stafford, from<br />

Stafford et al., 2008). Black scale bars in figures are all approximately 0.5 m and camera angle is near-horizontal in all feeder features<br />

photos. A = point source feeder showing prominent doming morphology proximal to master passage; B = typical feeder showing<br />

development at the top of a dolomitic interbed; C = complete hypogenic morphologic suite showing riser (white arrow), wall channel (dashed<br />

white lines), ceiling channel (solid yellow lines) and outlet (yellow arrow); D = well developed wall riser with associated wall channel (dashed<br />

yellow lines); E = linear riser developed along axis of master passage; F) dense cluster of small feeders above dolomite interbed with minor<br />

vadose overprinting below dolomite interbed.
