But it lost something in the process. Elevation Gain: 550 foot gain. "Weaker layers are removed by erosion more quickly," he adds, "leaving behind a layer of stronger material too thin to form a catenary curve. Potter established photo points and staged his climb again and again, just to be sure he got all the camera angles he needed.

Ironically, the Bloomers wasnt even included in the original proclamation. This allows gravitational stresses to be the dominant sculpting agent, Geimer says, leaving behind a smooth arc of rock held in compression.
