Quick Observation

Toured in the middle fork near the northern end of the flathead range today..  great coverage from the hwy to my turn around spot (6000 ish feet).  Some blow down sections definitely pushed me off the trail, but travel was easy and snow was of a very high quality.

No red flags save for a few predictable  ski length cracks around 3-4000 ft where a crust made a brief appearance.  Small glide crack on south side  of road right at mile 157.
