The rime on the rocks pointed me in the right direction for finding the fresh snow though. These beautiful feathery formations form on the windward side of an object, letting me know where the wind has been coming from, and thus where the snow has been blown to.
Only occasional snow showers in the weather forecast for the next 24 hours but it is going to be bitterly cold with -6 at 900m and -8 at 1200m forecast. The cold, dry snow will continue to drift in those conditions so careful route choice recommended.
