Graham Greene famously said that all writers need a chip of ice in their heart; Cusk can come across as the most beautiful ice palace of stalactites and stalagmites, and some people find her company, albeit by proxy, about as inviting as a long weekend in a walk-in frigidaire.
A key difference with lava stalactites is that once the lava has ceased flowing, so too will the stalactites cease to grow.
Essentially, it is still the deposition of material on the ceilings of caves, however with lava stalactites formation happens very quickly in only a matter of hours, days, or weeks, whereas limestone stalactites may take up to thousands of years.
However, vertical cavers have often encountered longer stalactites while exploring.
Ice can also form icicles, similar to stalactites in appearance, or stalagmite -like forms as water drips and re-freezes.
Ice stalactites may also form corresponding stalagmites below them and given time may grow together to form an ice column.
