Conditions on Joffre, Matier, Hartzell and Slalok today: 
- We set out around 6am from Joffre Lakes to get all four but backed out of Aussie (8am) as now there are some nasty icy runnels down it. 
- Matier NW face was lots of eventful breakable crust skiing but still good temps and in shade (9am or so) probably won't improve next few days. 
- We climbed the S ridge to get on top of Hartzell and it was getting quite soft by 9.30-10. Its NW face skied nice (combination of hard on W aspect and quite soft on N-ish aspect) 
- Climbing up Slalok the usual E slope before the ridge had good snow, before 11am. (Thanks for a nice track whoever put it in.) Up the ridge was easy cruising. The Stonecrop skied pretty well although quite wind affected. Half-way down we traversed right and skied the very right gully - it was OK. 
- Lakes held us up and down! The lower one will be mushy by tmrw. 
- Overall, temps on N aspects above 2200m were still cool enough (below zero perhaps) by the time we were there. 
- Watch for lots of wind affected patches/slopes and obviously for S aspects any time of day. 
- We were done by noon so keep in mind we were out before we could observe any big warming.

Quick conditions report from Garibaldi Neve Traverse (North to South) on Sunday: 
-road to Rubble Creek parking lot is snow free; snow starts at about 3.5km on the trail 
-all lakes are fully frozen (with no open watering holes at Sentinel Bay) 
-crevasses on the glacier section are well filled in 
-snow wasn't sun affected but freezing levels have risen considerably since then so I expect that is no longer the case 
-lots of avalanche debris at Ring Creek (as expected) 
-Gargoyles/Columnar hadn't slid 
-well trodden trail along the ridge from Elfin Lakes to Red Heather 
-snow coverage excellent on the trail all the way down to the parking lot and road from Elfin Lakes parking lot completely snow free (perfect scenario!) 
...A great day in the mountains of B.C....
