[MCR] Rockies, Wapta Bow Hut to Sherbrooke Lake

[Public Mountain Conditions Report]

I guided six guests across the Wapta from Bow Hut and out Sherbrooke Lake
April 3-6.

Bow Lake was frozen with no water on our crossing April 3rd. Skied over
several small piles of avalanche debris in the "Canyon".

We crossed the St Nic/Olive Col on the 4th and the Vulture glacier skied
fast and efficiently on chaulky snow ribboned with sun glazed crusts. The
wind and snow came in from the west on our afternoon trip from Balfour Hut
to ski the Diableret Glacier. Moderate to strong westerly winds howled
through the night and moved most of the new snow to leeward slopes.

April 5th, windy, white and a slowish wander up the low access to the
Nunatack slope/Hourglass and, eventually, Balfour High Col. We skied from
the high col on a compass bearing with rope and skins on. The icefields
have been wind hammered and presented a series of sastrugi, drifts and
blueish icey crusts. After about 1 kilometre we could see some and got rid
of the rope and skins and skied broadside to the wind to the Scott Duncan
Hut. Constant moderate to strong winds through the night.

April 6th more whiteout and more wind, we faced into it skiing towards Mt
Niles. We descended into the gut with wind deposited snow underski and
fields of blueish sun crusts on all windward aspects. The Shiesser/Lomas
was gained from the gut immediately below the East Face, and true summit,
of Mt Niles (read not that far down). I was happy to find less than 25 cms
of wind deposited snow that soon gave way to the crust on the steeper part
of the climb, not much worry of windslab because the wind had spread the
new snow thin as marmite on toast. Variable skiing on drifts and crusts to
treeline and then some nice dust on crust to Sherbrooke Lake. The lake
skied well with no water and a couple cms of spongy snow on, you guessed
it, crust. The lower cat track to Wapta Lake (Great Divide Lodge) has lots
of pine needles and boughs and several trees down. Only moist-to-ground
snow I saw was there if you stepped off of the track.

Happy trails,
