i don't believe that a slope of less than 20 degrees could produce a 300 X 300 avalanche. It could get run over or entrain but not trigger.
I would be getting home over terrain like this and avoiding any runouts or steeper terrain
Sliding sounds more like the hazard here than avalanches, so long as the crust remains intact. That is why I would spread the group.
Skiers would have to be very good and capable of handling hard crust conditions.
because of deeper problems, for the loose avalanche, I would space skiers out
actually I would space them out so that if one wipes he/she doesn't rip out someone else
because of deeper slab
if the Cr is intact, then lets go carving, if Cr is broken down stay away, spacing is for collisions not avalanche safety!
assuming its thawed and running No

This is a bit confusing as the scenario is trying to mix loose dry avalanches with pwl. 30cm of new snow and natural activity indicates a high likelyhood of triggering if you pick the wrong (steep) terrain. The larger concern would be a step down fracture into the pwl, but that issue is irrelevant since the question is limited to loose, dry avalanches
sounds like the scenario is also set up for loose wet avalanches
How can there have been 30-60cm of recent HST when a "lemon layer" is only 10cm deep?
Biggest concern here seems to be the SSL down 60 to 90
Snowhat serious? you must be getting as tired of writing this survey as I am of answering it?
Once again, the situation seems wierd, because it sounds like more of a slab avalanche issue.  I almost pressed the "unrealistic" button on the last screen.

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
would be OK except the shape and the terrain trap
slope not steep enough to present a hazard
unfavourable steepness outweighed by favourable char acteristics.
Loose dry avalanches possible but small expected size limits consequences
angle not steep enough for loose dry avalanches
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
