Over and under achievement

This achievement was proposed in the past, but has been rejected, because it was combined with the Stacking achievement to make the Multiple elevations achievement. Please read the discussion page for more details.

As per the page proposed achievements: If an achievement has strong opposition and the reasons for opposition are not resolved through discussion, then the proposed achievements category is replaced with the rejected achievements category, the reason explained succinctly on the page, and the page otherwise marked to make sure it isn't confused with an achievements page.

This achievement would mark when a single hashpoint is reached at substantially different elevations. As an example, I awarded myself this achievement (as a gratuitous ribbon) for reaching the 2010-08-05 45 -122 hashpoint both on an elevated freeway ramp and on the ground, several dozen meters below. Other examples could include the top and bottom of a cliff with a substantial overhang, a balcony and the sidewalk beneath, different floors of a tall building, or the base and upper limbs of a substantial tree.

There could be occasions when this would overlap with an Air Geohash or an Underground Geohash, but it is a somewhat different and, I think, noteworthy feat.

Ribbon

This is the "gratuitous ribbon" I made myself:

Michael5000 earned the The Over and Under Achievement by reaching the same hashpoint at two different elevations (45, -122) geohash on 2010-08-05.
