Loud Whumpfs, big slabs, and propagation

Once to the right of the top if bacon rind we made a pit and discovered a weak layer at 6 inches deep propagating at an ECT rating of 6. Continuing on with the test we discovered a large layer (the same weak persistent layer we've had all year) about 60 cms below the surface and the slab moved as a whole at an ETC of 22. Super unstable snowpack so we decided to keep it below 30°. Then when skinning along the top we had to full whumpfs that sounded like a train was starting up. Finally we had a very unfun situation on a slope nearing 30 degrees that propagated and my partners said they saw it fall behind me. Overall super unsafe and I'd say avi danger was considerable. Those sweet 35° slopes are asking to slide. We also observed an old avalanche. Stayed out of harms way but am definitely getting new shorts.
