On a north by northeast direction from a' Chailleach, the mountains have been folded extensively. Two corries overlook Loch a' Bhraoin to the north. The first of these is formed by the mountain Toman Còinnich at 935 metres, forms the corrie that contains Loch Toll an Lochain, where the direction of the corrie faces the northern end of the loch, similar to a giants seat. Further east again, is Sgurr Breac, which forms the peak of the second fold, which creates the corrie, that is intersected by a long shallow valley that descends from 600metres down to the north-east end of the loch.
