Gate to the Middle of Nowhere

Gate to the Middle of Nowhere
Looking over White Path Moss towards Stanage Edge and Stanage Pole (but lost in the mist).

White Path Moss is an extensive flat area of peat bogs and watery pools, very difficult to cross except on a very subtly elevated shallow ridge known as Friar's Ridge.

It is generally accepted that this is a nivation platform, a.k.a. cryoturbation platform. These form where a permanent but relatively shallow snow-patch (as distinct from an ice-sheet) has existed for an extended period of time, perhaps thousands of years. They are well-known from periglacial environments, past and present-day. Beneath the more-or-less stagnant snow-patch, there can be considerable freeze-thaw action, breaking up the top surface of the underlying bedrock and causing it to flow slowly down even the shallowest of slopes. The effect is for this flow material to 'fill in' any pre-existing hollows and generally smooth out the existing landscape, ultimately tending to become a flat surface. In this locality the nivation platform is a broadly linear feature, parallel to the outcrop of Stanage Edge and set back from it by as much as 1.5 km.
