Back at it after a few months’ break :)

Now, if you've been on our tours, you've undoubtedly seen our magnificent Flowing Stone of Time. Rimstone is formed by calcium bicarbonate leaving behind trace amounts of calcite as the water flows down the rocks. But what happens when that water reaches the bottom? Rimstone happens! When the water reaches the bottom, it pools up. The force caused by the water flowing down from the rock causes the water to push up against the edge of the pool and that's where the calcium gets deposited. As the water is pushed over time, it creates the small edges of the pools that you can see in the picture above.
