XC Ski'd both the West (sans tech-loop) and North this afternoon.
West Long Loop = 12" wide flat, hard packed path down the middle of the trail. Fat bike heaven. Cleared a low leaner just after the .5 marker with a folding hand saw. There was another one just before it but too big for folding saw and is passable. Lake Loop was not bike freindly. Only an old set of XC ski marks and one pair of footprints visible meant soft conditions.
North Loop = 12" wide flat, hard packed path down the middle of the trail. Fat bike heaven. Cleared a small low leaner at the old barn foundation with a folding hand saw. There was another one just after it but too big for folding saw and passable if you duck really low.
Couple overall observations......
Snowmobile tracks go from Tech Loop/Long Loop intersection all the way to the parking lot (they originate somewhere East(?) of the Tech Loop). They then continue from the North exit to the lake bench overlook. Apparently ice fishermen have dragged their shanty on a sled behind it to get to the lake
I'm not clear on the rules for snowmobiles at Holdridge but I don't think they are supposed to be on the trail.
It was 38 degrees when I got back to the car!!!! That nice flat hard packed path was starting to get soft. I recommend avoiding any riding until the temps drop back down in a few days. Otherwise there will be some nasty twisting frozen snow ruts to ruin any fat bike riding.
