Tryfan. Underfoot: graupel, changing to ice under graupel on summits.
Weather: Stiff westerly breeze on the tops, otherwise sheltered. Some snow showers but largely clear and dry.
Scramble the North Ridge of Tryfan. Avoided the towers by dropping down into the top of Nor Nor Gully. Skipped Bristly Ridge, took the scree slope to the left, covered firstly with snow, then some ice (but climbable without crampons). Traversed the top then descended via Y Gribin.
