deflected
The deflected subfield of the Stalactite field should record stations where a deflected stalactite can be found.
Deflected stalactites are stalactites which show some noticeable slant from the vertical. They grow this way primarily by air movement causing more minerals to be deposited on one side from evaporation or deposition. They can occur singularly or in clusters. If a deflected stalactite is found, they can often be found at other nearby stations where conditions may be similar. The airflow which caused the deflection may still be present or conditions could have changed such that airflow is no longer evident.

soda straw
The soda straw subfield of the Stalactite field should record stations where soda straws are observed.
Soda straws are thin-walled tubes of calcite or aragonite which hang from the ceiling but may be found broken on the floor. They have a constant diameter of about the width of a drop of water and may be any length from a few centimeters to multiple meters long. They may also exhibit active dripping or hanging drops of water but can also be found dry and, at least temporarily, inactive. They can appear singularly or in clusters, sometimes great clusters. Examine the ceiling especially along cracks or where other stalactites are formed to find soda straws. And don't forget to look at the floor. Broken straws can also be found cemented into flowstone.
