[MCR] McMurdo Notes

[Public Mountain Conditions Report]

Just out from McMurdo Hut in the Spillimacheen Range of the Purcells (Jan. 10 -14). Overnight lows to -25C following the last warm storm cycle tightened up the pack quickly.
Mid-thigh boot pen on arrival settled out to a consistent ski pen average of 25cms. S/ E aspects in the alpine sun offered perfect windless powder in mid-day temps around -10C.
Alpine HS 240cm +. The Jan 9th storm overloaded one big N-facing cornice 7,200', dropping blocks on steep fans below to trigger sz 2.5 mixed slab / loose snow avalanche. 
The slab crown looking approx. 60 cms corresponded to compression tests (CTH 24) we found at the same altitude SP on decomposing old surface hoar 2mm. Rutschblock tests 
(score 5) on S aspects at this altitude only showed weakness at the storm snow interface down 35cms.

The Spilli logging road is active and well-maintained to km 35 (limited parking area). Sled access road is bladed at least once a week. Hut and kitchen is well equipped for 5. 2 Coleman lamps
and propane cook stove require cartridges; 1 Coleman white gas lamp also. Suggest taking an axe, not much life left in the one there. Well-stocked woodpile. Vermin free 5 days. 
Lots of midnight bunnies tho!!
