Ondal Cave, at least the first part of the cave, was much wetter than Gosu Cave. A subterranean stream flows through much of the cave and plexiglass roofs have been erected at points along the way to prevent visitors from getting soaked by the water still dripping in large quantities from the ceiling. This is somewhat ironic, seeing as we came here to get away from the rain.
This is another flowstone stalagmite with draperies, but it has a much different feel than similar formations in Gosu Cave. Most obviously, the formations are glistening with water. They are also tinted green, most likely because of differing mineral composition (copper, maybe?). In addition, the canopies and drip splash tiers tend to be more rounded. I’m guessing the wetness of the cave has something to do with this, but I’m not really sure how.
