Avalanche Atlas

Crow Valley

Access to this area is from the Waimakariri River or via Avalanche Peak. Several obvious avalanche paths cut a swathe through the east flank of Mt Stewart leading into the Crow River. Once active these paths also initiate large rockfalls. Upstream of Crow Hut the entire valley is potentially an avalanche run-out zone from the faces of Mts Rolleston, Lancelot and several guts leading to the Avalanche/Rolleston Ridge. Extreme avalanche behaviour is possible from May to November each year.

  • All parties travelling via Avalanche Peak need to be avalanche aware as wet sluffs are possible into the head of McGraths Creek, and the standard descent scree/snowslope into the Crow has potential to release because of poor anchoring and face deloads off adjacent bluffs.
  • The gut leading to the East Crow Glacier at the head of the valley hosts very large wet & dry avalanches each year, in some years run-out has been 200-300 metres along the valley floor.
  • All slopes under Mt Lancelot are swept by moderate size avalanches each year, many of these initiate at ridgeline and become airbourne for the final 200 metres.
  • The Crow Glacier icefall can drop ice at any time of year.
