Generally unfavorable, except the 20 degrees or less makes it a pretty benign place.
The varying slope angle with some tree islands as well as the absence of any wind effect in a wind slab situation should make this manageable if you can avoid the terrain trap. Also the concave shape is favourable.
If there is no wind slab here and the slope is in the mid 20 degree range, I think you could travel over a terrain trap even if the slope is unsupported. Not sure how these characteristics require "Full commtment"
Not sure how a 20-30 degree slope with no terrain trap can be unsupported
Caution surface hoar or overhead hazard. Otherwise favourable.
Regarding Scenario 1 - answers depend on severity of the terrain trap - big difference skiing a 20d slope in the trees versus a 20degree slope over a cliffband in those conditions
i dont like terrain traps and full comitment, its always nice to have a second choice
Mature timber and moderate steepness make it more favorable, terrain traps make it less
shallow HS,full commitment and terraintraps are not a good combination, the unly thing in favour is the angle
A bit odd, if it produces large avalanches, how do the trees stand up? Are the trees on ridges I can use to get around?
not exposed to sunlight and additional decission points
apart from hazard associated with hitting logs in shallow snowpack!
i dont know if you can have a unsupported slope with mature timber, i believe the timber in itself would make it supportive
crossloaded and shallow, potential for large releases
not steep and small releases
I would like to make a point here, also regarding the first 2 scenarios. There is a huge difference if a slope is 20 or 30 degrees, or in the first scenario 30 - 40 degrees. It takes a lot of unfavourable consitions to make a 20 degree slope slide, but you but it in the same category as a 30 degree slope. Also, I don't know any open slopes which are not exposed to sunlight and protected by any windtransport.
Consider overhead hazards.
Contradictory characteristics: crossloaded slopes don't have a uniform snowpack.
More info on the terrain trap would influence my decision
I have to aasume there are no dangwrous slopes above, therefore slope size is inconsequential
small release, planar slope, no vegetation
steep crossloaded slopes will always be unfavourable
incline
no wind effect, small releaase, timber
additional decission points
given the slope angle it is unlikely the slope will slide, but it could fail and propagate to release a slide overhead.
I'm confused by the slope angle being less than 20 degrees yet capable of avalanche 300m x 300m
steep with a varaible snowpack
I'd look for signs of loose dry avalanches to see if they have cleaned out the slab
Steep with a terrain trap are the key features
would be OK except the shape and the terrain trap
20 degrees with terrain trap is hard to imagine
again - how protected is it from the wind in question
rating only with respect to avalanche hazard.
avoiding the glade with the 25 x 25m potential of course
corn snow conditions, 40 degrees + mature timber - sporting!
oh my god... how much longer... i'm losing it.
40 degree into a terrain trap
Wet slabs are not my specialty. My biggest concern might go back to the fact there is a terrain trap.
slope not steep enough to present a hazard
unfavourable steepness outweighed by favourable char acteristics.
As long as temperature remains below freezing.
Loose dry avalanches possible but small expected size limits consequences
angle not steep enough for loose dry avalanches
again it's the terrain trap, I just don't like skiing around them
can't we go anywhere without these god damn terrain traps, agian I don't think its steep enough
the terrain trap again
slope angle is steeper and it would be very unfavourable
If it's less than 20 degrees and planar, it's not avalanche terrain!
But, the sluffs do need to be managed.
the slope sounds a little scary, but I generally feel pretty good about sluff management
For deep slab instabilities, need to also know how the terrain is affected from above
