Structured overview
Route summary
Jacks Stream and Stony Stream offer interesting touring across a range of terrain and aspects.
The south-facing slopes can hold powder well after a storm has departed.
The heads of the streams are relatively low angle with steep headwalls, couloirs, summits, and boot-pack options.
The area is described as suitable for a camp and several days of exploration in good conditions.
Access notes
The original report used helicopter access from Glentanner to the ridge dividing Jacks Stream and Stony Stream.
The author notes the walk out of Jacks Stream is overly arduous for most, though possible.
Intermittent mobile coverage exists from ridge tops at the head of the basins.
Safety notes
Take both Mt Cook and Ohau weather/avalanche forecasts into account because local weather can differ across the range.
The terrain includes low-angle basins, steep headwalls, couloirs, and short steeps that need conservative snowpack judgement.
Expect possible overlap with heli-ski terrain from mid-July to mid-August.
