As promised, I waited until I was reasonably sure the groomer would not sink in wet snow, as happened to Brian at PAXC, and then towed a Tenderizer around M and the S/H spur (~5 km), three passes. I attempted to leave the classic "track" alone because I will not likely be able to set another. It does not appear to be enjoyable or much in use.
The skate skiing is much improved from its former condition. Berms from the edges of the Tenderizer were unavoidable and there are many ice cubes in places. As each day warms up, the snow will change from fast, frozen granular with ice-cube patches and hard ruts from yesterday's skaters, to mostly acceptable skating with treacherous frozen sections in the shade, to somewhat slushy sections. Rocks may be very close to or above the surface at any time, where "close" depends on how soft the snow is!
