Snow at 500m, at 600m elevation (between 3 & 4km on the Elk main) blocked our way for the 4x4 . Very challenging ski conditions (aka frozen snow mobile tracks) until 1000m. Breakable crust to 1250m. Above that about 5cm on top of the crust and soft underneath it. Ski pole in around 1300m was about 70cm to the bomber lower snowpack. Skiiing was enjoyable above that (see photo).
