Europe
Continental Shift
Located in Þingvellir National Park, Silfra is a rift in Iceland where the North American and Eurasian plates are separating at a rate of two centimeters per year. Filled with glacier water, the clarity is prized among adventurous scuba divers, who can throw on a dry suit and place their hands on two continents simultaneously.
