From Eden to Everywhere

At the top of Mount Eden (the highest volcanic peak in the city), there's a neat brass monument.  It's circular and looks something like a sundial, except that instead of hours of the day it has names of international cities, with arrows and distances.

It pointed the way back to North America, way off to the northeast.

We circled around the crater and from this point, across miles and miles, we're facing approximately back home.  Can you see us waving?
