Gorge km15: Snorkels and wind lips

We skinned to the summit of km15 ridge. Skied the south western facing slope. Top section had a buried crust (sun crust?) under 15-20cm of powder. Mid section yielded deep powder turns with ordinary sloughing. We skinned back up the ridge to the summit for exit, the eastern ridge had become covered in large unavoidable wind lips and some windslab as well. It was blowing pretty strong and coming down quite a lot as well. The drive up was ordinary and the drive down was pretty puckering with a extra 15 cm on the fsr.
