we spent the last two days in the Asulkan drainage & Little Sifton regions. 
things are still relatively winter like above 2200m & good skiing was found on 
more Northerly aspects.

on Apr 2 we headed up towards Saphire Col via the Mousetrap.  AM conditions 
found a firm trail to above the Mouse Trap (1600m) and then improved to dry 
snow with no crust above 2000m in the shaded areas.  coverage on the glacier 
was over 3m of snow in areas checked, but numerous sags & open crevasses are 
visible.  we treated the snow bridges with a healthy dose of caution & remained 
roped up for the majority of travel over ice.  we headed up Castor peak & found 
extensive wind loading & cornices along the ridge.  boot packing was deep in 
facets & new snow, with sections waist deep.  looking South along the ridge 
towards Pollux & Leda, conditions appeared similar and travel would most likely 
be quite slow.  we returned down through the tree triangle & enjoyed great 
skiing with ski pen about 20cm on average.  

skies stayed mostly cloudy with some flurry activity with 5cm of accumulation.  
temps were mild but stayed below freezing.  solar input (sunshine) was a 
minimum & no moist snow was encountered above 2000m.  winds were moderate thru 
the Col & were transporting the snow into immediate lee features.  no shears 
(hand shear tests) were found in the top 50cm, nor any results occurred from 
ski cuts.  some isolated small soughs have occurred out of steep (40 deg or 
more) terrain.

Apr 3 we did the Little Sifton traverse.  the track up Grizzly shoulder is very 
firm & slick.  ski crampons are strongly advised.  on that aspect below 
treeline a 5-10cm melt freeze crust is present.  we were getting clean but hard 
(to trigger) shears under this layer. above treeline on the sunny aspects, a 
2-4 cm crust was present under 5cm of new snow. 

skiing down into the Hermit had great turns down to the toe of the glacier, and 
then careful use of subtle aspect features (looking for areas shaded from the 
sun & free form overhead hazard) had more good turns down to  2100m.  from 
there to 1800m, unsupportive & breakable crust was predominate and skiing 
sporty.  below 1800m skiing improved with the crust being supportive.  about 
100m above the hi way elevation the snow became moist & grabby.

weather was similar to Apr 2nd with less wind & no snow transport noted.

all in all some good spring skiing to be had with careful consideration of what 
has been sun effected, and where the good snow still remains.  we strongly 
recommend throwing the ski crampons in the pack - it will make life easier on 
the lower elevation skin tracks.

happy turns!
