Hundi Stack Natural Arch (West)

A natural arch aligned WNW/ESE. Quite similar to the arch at Gorsins Geo in being through the neck of a hammer-head promontory.

Length calculated from NGRs. The east one is much better lit in the Bing Aerial.

Bing Aerial also shows a possible cave entrance. This may be another arch - Pastmap Aerial shows that there is a mini-geo on the NW side.

Bing Aerial showing a bit more of Hundi Stack. The lighting is such that SE facing surfaces are better lit than on Pastmap. Note that there appears to be a possible cave entrance in line with thsi arch. It is marked 'cave ?'.
