It may not be readily apparent what the Okotoks Erratic has in common with world heritage sites such as ChichEn Itz-, the Titantic, the Parthenon and Machu Picchu, but it is one of two Canadian sites that has been selected by the CyArk 500 Challenge, an international project that is digitally preserving vulnerable, culturally significant historic sites around the world.
