The chenille/pool field should be used to list stations which have pool spar crystals.
Pool spar are well-defined crystals that grow under the surface of pools of water. They may be found lining the floor, sides and under shelfstone of pools and dry pools. Chenille spar are a subset of pool spar. Individual pool spar crystals are rarely large and most often small but the clusters of crystals can line the entire underwater surfaces of a pool.
Chenille spar are long drapery-like crystaline formations which form just below the water surface. They are closely related to pool fingers -- both have the same origin, calcite crystals growing on microbial filaments. The primary difference between pool fingers and chenille spar is that chenille looks more like a drapery while pool fingers are more finger-like. Chenille spar rarely gets more than a meter in length and individual crystals are usually so small as to make the formation look velvety.
Look for pool spar and the chenille variety of pool spar anywhere pools have formed or may have once been. Be sure to examine under shelfstone and ledges that may be covering the pool and hiding the spar. It doesn't take much of a pool to form pool spar. Pool spar can even form between the gours in a series of rimstone dams.
