Last weekend, we travelled some around Wisconsin. On the way to Oshkosh, we stopped by Cave of the Mounds, which we never visited before. It was well worth the time. While the cave is not impressively large, it has a lot of rock formations, stalactites, and stalagmites, and pools to reflect the light and structures.
Before the tour began, we had few minutes to spare. Afternoon light was coming right through the store window, shining through pieces or rocks and granite tableware. It was a great fun to photograph it.
