Rauks, Caves and Cliffs - Ancient Coral Reefs

After the weight of the ice age glaciers receded, Gotland has raised up from the sea. The limestone that makes up the island has eroded at different rates. Coral reef limestone was the hardest, so remnants of those Baltic reefs remain as rauks, cliffs and caves. This rauk was near Lickershamn, north of Visby. Ingvor noted that it has the typical Swedish potato nose. After that we could see profiles in many of the rauks.
This is Chuck in front of Jungfru rauk at Lickershamn. It is about 12 meters high, and 20 meters above Baltic sea level. Translated from the website link: The "Maiden" rauk has gotten its name after the tragic story about the Maiden Öllegard and her beloved Helge, which ended with them throwing themselves into the sea. (Which reminds me of a pun: She threatened to jump off the cliff, but it was only a bluff.)
In June, Andrea, Haylie and I toured Lummelunda cave. This is the photo of the original cave opening, which only skinny kids could crawl into. Since then, they have built an opening for tourists (and grandmothers), and an interpretive center. They showed this video before we went into the cave, about the three boys who discovered it.
We took a nice hike at Högklint, just south of Visby, where Haylie and I explored a shallow cave.
