For this field note, I am going to flex my geology (the study of Earth) muscles and talk about one of Slovakia's most unique features: caves. Slovakia has six public caves listed as world heritage sites, rivaling much larger countries like the U.S. and China. Each cave is different, making them all worth a visit. I hope to visit as many caves as I can during my travels around the country. Even though caves aren't alive like plants or animals, they are very delicate, so protecting them for future generations to explore is very important work.
If you've ever been inside a cave before, Slovakia's caves will look pretty similar at first glance. Most caves are made from limestone, a rock which dissolves in water over millions of years. Limestone is the rock which makes the crazy-looking stalactites and stalagmites (English words which describe the big rock pillars hanging down from the ceiling or sprouting up from the floor). I have been to two Slovak caves so far. One was the Demänovská ice cave, which is normally full of ice, but due to climate change is not full of ice anymore, and the other was the Ochtinská aragonite cave, a very rare type of cave with aragonite crystals growing on the walls and ceiling. You can see my pictures of the caves on the side.
