- 1–2
Slabs that formed over a week ago sit on top of weak snow. Triggering these slabs is becoming less likely, but the possibility remains. Slab depths are in the 1-2 foot range, with previously wind-loaded slopes holding the thicker slabs. Watch for areas where the wind built thick, firm pillows as you ride. Obvious signs of instability such as shooting cracks and collapsing, may not present until you trigger an avalanche. Ride one at a time across steep terrain, use islands of safety when stopping and communicate your plans with your partners. Terrain traps like creek beds and steep slopes above road cuts are common on Togwotee and should be viewed as suspect.
