Attempted to ski to the Farnham Cabin on Sunday. Was able to drive a pick up with chains to the landing about 4.5km from the cabin on the Farnham Creek FSR. Was able to skin from there. We turned around at the last prominent slide path on the upper 4X4 road (about 15 mins from cabin) due to a size 2-3 slide blocking the route: debris was over our heads and due to the shape of the steep gully/high embankment, going around it felt generally unsafe, and going over it was difficult. The 4x4 road had deep fresh snow and the ski down was surprisingly enjoyable.
