Windslab

24th February 2020

(Above) Broken ground of heather and snow leading into Coire Choille-Rais. A complex distribution of windslab around at the moment with variable winds and persistent snow showers. The hope was to catch  N, NE and E aspects on the way in and get a look at some high (above 850m ) SW and W on the back wall of the coire.

(Above) Reality check….. persistent snow showers and poor visibility today meant above 600m – unless I stumbled across it the chance of seeing very much was pretty limited. Underfoot – NE and E aspects had moderately bonded slab.

(Above) Weakly bonded slab developing here on a Westerly aspect at 800m – on fairy easy angled terrain.

(Above) Back wall of Coire Choille-Rais. Some reasonable ice build up developing on the crags –  formal pit today was on the slope just below ice fall, to right of photo

(Above) A fairly shallow affair (thankfully!) new slab overlies hard icy layers

Further windslab development is expected above 850m in this next period, mainly on NE and E aspects …. with optimum slab building 25 -30mph winds and cold conditions
