Calcite (Inventory)/Helictite/subaqueous
From LagWiki
The subaqueous field of the Helictite subsection of the Calcite section should be used to record any observation of subaqueous helictites.
Subaqueous helictites are helictites which form under water. They are formed much like other helictites, but they do not bifurcate or split. They appear as erratic tubes associated with a pool or former pool. They can be observed attached to the rim or walls of the pool and angling downward. They are usually located a couple of meters (3 to 6 feet) downslope from a large gypsum deposit or formation.
Look for subaqueous helictites on the rims and walls of pools or former pools especially if gypsum is nearby.
