continued… The path led to another staircase, which ended in a long, relatively thin cavern. Here was a shot looking back at the staircase from deeper inside the cavern. You can see the staircase that led up to the entrance in the background.

In this cavern, she got more into the geology of how the cave formed. This portion of the talk was similar to what we’d learned at Raufarhólshellir. We were again thankful that we’d seen the Lava Show (twice!) — the idea that running lava could form a giant hollow cave was actually counterintuitive. We probably would’ve had trouble wrapping our heads around the phenomena had we not actually seen them form in the demonstrations.
