Photo #1 — Road coverage had some patchy & icy areas at lower elevations due to warm temps/rain. Nikki and I determined that the plus side of this was that we had a multi-sport day to celebrate the solstice: sledding, ice skating, and dirt biking all without leaving our sleds.
Photos #2-4 — Difference in snowpack depth and structure nuances between aspects. We found an isolated secondary, very thin, eggshell-like rain crust on a N aspect near 8800' where orographics likely squeezed out a small bit of warm moisture. Paying attention and being surprised—what observation is for.
Photo #5 — The splash of the track paints a picture.
