Caving: ice crystals!!
On Mon nite, mom and I went caving at a cave is named Raufarhólshellir. I wore a caving helmet with a bright light so I could see in the pitch black. I liked the cave wall, it looked like smeared, smooth lava in bright oranges and black colors. The cave floor was covered in ice cone formations, they looked like clear crystals! I took a huge ice crystal and lava rock from the cave, home for my collection.
