IIn June 2022 I had the pleasure of exploring lava tubes in Iceland. I was first greeted by large fields of Lúpína, a vibrant purple flower carpeting areas all throughout Iceland. As I got further from Reykjavik the landscape quickly changed. I found myself surrounded by the Leitarhraun lava field, created by an eruption of a volcano on the Reykjanes Peninsula 5200 years ago.
This would be the first time I had explored a lava tube, so I was excited. They are much different from the solution I had already experienced. Creation of these caves couldn’t be any more different. While solution caves are created by water, lava tubes are created by fire. Though the lava tubes I explored were wide and tall, navigating the floor filled with collapse was more challenging than I expected. The climb up and down the collapse was not physically challenging, but instead require more cautious planning for every step. A fall from a misstep onto the jagged rock carpeting the floor could be fatal.
I hope to return soon to collect sample of bacteria that flourishes in this unique environment.

This lava tube is found in the Leitarhraun lava field and 1,693 ft long. Its ceiling collapsed a few thousand years ago and deposits cover the floor, except for the first 328 ft, which are perpetually covered by a thick sheet of ice.
