When I saw the damaged end of a saguaro arm where the blackened protective material had cracked, showing the lighter material underneath, I was reminded of lava lakes in Hawaii and Iceland. The lava on the surface cools and hardens and can sink into the less dense molten lava via a process called crustal foundering. It took me a while to find the time to bring my macro setup on a day when there was little wind, and even then it took me a few attempts as the breeze was often stronger than predicted.
The National Park Service has a description on their page about Hawai’i Volcanoes National Park.
