Rescuing people from underground is difficult and time-consuming, and requires special skills, training, and equipment. Checking that there is no danger of flooding during the expedition.
How old is the oldest stalagmite?
Limestone stalactites form extremely slowly – usually less than 10cm every thousand years – and radiometric dating has shown that some are over 190,000 years old. Stalactites can also form by a different chemical process when water drips through concrete, and this is much faster.
Are stalagmites hollow?
Most stalagmites have rounded or flattened tips. There are many other types of mineral formations found in caves. Some deposits are named based on their appearance, such as a showerhead, which is a hollow cone-shaped formation, narrow above and broad below.

The icicle-shaped formations are called stalactites and form as water drips from the cave roof. Stalagmites grow up from the floor, usually from the water that drips off the end of stalactites.

How much do cavers make?
BLS salary data highlighted the average salary of geoscientists in general, but not speleology specifically. As they have similar skills and qualifications, we can expect pay and job demand to roughly equal the broad area of geoscience. In 2017, it was reported that the average salary for a geoscientist was $89,850.
What happens if you touch a stalagmite?
Limestone stalagmites. Stalagmites should normally not be touched, since the rock buildup is formed by minerals precipitating out of the water solution onto the existing surface; skin oils can alter the surface tension where the mineral water clings or flows, thus affecting the growth of the formation.
Do stalagmites hang down?
“When mites crawl up, they pull their tights down.” That’s how I always remembered it Stalactites hold tight to the ceiling, and Stalagmites might grow to meet them. Stalagmites might reach the roof.
