We prepare to leave Warderick Wells and I just had to take one more picture that really shows the channel that the current had "dredged" over the years creating this perfect mooring field for boaters. The eastern shore of the Cay is home to reefs formed by stromotolites, the oldest evidence of life on earth. These fragile, flat gray reefs date back to 3.5 billion years and were thought to be extinct until discovered in 1983.
