stalactites
Hanging mineral formations
Stalactites are mineral formations that hang from cave ceilings, created over thousands of years as water drips through rock and deposits dissolved minerals.
They grow downward like stone icicles: The flashlight revealed stalactites covering the cavern roof.
The matching formations that grow upward from cave floors are stalagmites—stalactites hang tight to the ceiling.
