Today we met at the Walsingham Nature Reserve.
We took a tour around the park to check out the natural caves in the area with Robert Chandler. He started off the tour by showing us the native plants found in Bermuda. After an introduction about the endemic plants and mangrove ponds we continued down the unbeaten trail to check out the natural cave formed from limestone. The limestone bedding in Bermuda formed between 10,000 and 1.6 million years ago out of fragmented skeletal remains that accumulated overtime to form a hard calcium carbonate layer.
Limestone is very porous and allows water to move through it which cause these caves to form. It is easily eroded and over time the water carves out large sections to create caverns. Water that drips from the ceiling of the cave deposit calcium carbonate and forms stalactites and stalagmites that look like rock icicles which took tens of thousands of years to form at this magnitude.
As a group we went down the street to see the famous crystal caves mentioned by famous author like Mark Twain. It was discovered in 1905 by two 14 year old boys who went to chase their cricket ball into a dark hole. The boys repelled into the cave with only a gas lantern for light. When we were at the end of the cave the guide turned off all the lights and it was pitch black and you couldn’t see your own hand in front of you. It was amazing the see how big this cave and the giant stalactites that formed over thousands of years, and the crystal clear water below the floating walkways.
