San Andreas Fault

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception 

In 1906, a giant San Andreas Fault earthquake carved a trench through Portola Valley, California. More than a century later, geologists believe they've proved the San Andreas Fault plowed alongside the valley's western ridges, ending decades of debate caused by a poorly reproduced historic map. http://oak.ctx.ly/r/9363
