Geocache Description:

The cache is NOT at the posted coordinates.

In a few days, I hope to increase my highest elevation cache find from 7700 feet to over 14,400. (30 August 2017 EDIT: Success!) With elevation on my mind, I was motivated to create a puzzle about mountain peaks. I learned about topographic isolation, a term with which I had been unfamiliar. When someone observes, "this here's the highest spot around fer miles," they are talking about topographic isolation, which is sometimes called the "radius of dominance."

Mount Whitney posts a pretty impressive figure for topographic isolation: one need travel 1646 miles from Whitney's summit before another spot as high can be found. Mount Whitney's radius of dominance is 1646 miles. This brings us to Jarvis High Point, the subject of this cache. It too has an impressive radius of dominance, 1151 miles. Unlike other summits with high topographic isolation, however, Jarvis stands at an "impressive" elevation of -- wait for it -- 23 feet! Yep, in the middle of the South Pacific, 23 feet is the highest natural spot for over 1000 miles!

You'll find the physical container by heading to the coordinates (NN NN.NNN, WWW WW.WWW) defined by these questions:
