Windslab
5th March 2009
(Above) NE ridge of Sron a Ghoire today. Big pillows of soft, weak windslab.
(Above) Small deep slab avalanche at 550m on NE ridge of Sron a Ghoire.Only 20m across and ran for about 15m but this is really low altitude on modestly angled ground. Higher up, windslab accumulations are much deeper and more extensive (and even less stable). The crownwall drifted over (rapidly!) during heavy snow showers but the weather cheered up dramatically after midday. Drifting continued more or less all day even when it wasn’t snowing.
(Above) Ski tracks through fresh snow (windslab).
It was a right flounder at times today with really tiring trail-breaking. Check the depth of snow exposed by ski tracks – some drifts are more than waist deep.
