Within the Great Bowl
The descent requires two ropes to manage the distance, and six spikes pounded into the rock to secure them. Recovering the spikes will be difficult, but not impossible. (DC 5:15 Might task. Also, could you each please make a roll for the descent, DC 1:3.)
Once the slope eases to the extent that ropes are no longer needed, the way down is still tricky, and your footwear will be need to be emptied of sand and pebbles regularly.
