Observation: Turnagain

Touring up Tincan, noticed that a very thin crust had developed overnight. It
was barely noticeable, and sat an inch or two under the surface. It felt like a
melt crust, although the Sunburst weather station said that temps were in the
low 20s last night. The day before (Saturday), the crust was not present in the
same place. The crust was barely noticeable when skiing, and was not reactive,
but might cause problems down the road.
