Natural Arch through the Connis promontory from Muckle Geo of Huni to South Gunnarwark.

The BGS overlay has the Connis ridge/promontory as sandstone, siltstone. It shows a dyke ending at the base of the promontory and in line with it. From photo 1 it looks as if the promontory is a continuation of the dyke.
