Quite possibly I’ve walked from one tectonic plate to another before, but I can now say for sure I’ve done it, with the help of the illustrative Bridge Between Continents on the Reykjanes peninsula. The bridge opened in July 2002. For scale, it’s 18 meters (59 feet) long and about 6 meters (about 20 feet) above the canyon formed by the drifting on the North American and Eurasian plates.
Some cool rocks, but without the Bridge I would have had no way of knowing the significance of the canyon. But that’s often how the world is. Anyway, it keeps things in perspective to think on geological time scales, although the informational signage said the drift is around 2 cm (over 3/4 inch) a year, which is more than I would have guessed. Over my lifetime that’s almost 3 feet!
