The Roman History · Amm. 15.10.4

For to travellers who reach it from the side of Gaul it descends with a steepness almost precipitous, being terrible to behold, in consequence of the bulk of its overhanging rocks. In the spring, when the ice is melting, and the snow beginning to give way from the warm spring breezes, if any one seeks to descend along the mountain, men and beasts and wagons all fall together through the fissures and clefts in the rocks, which yawn in every direction, though previously hidden by the frost. And the only remedy ever found to ward off entire destruction is to have many vehicles bound together with enormous ropes, with men or oxen hanging on behind, to hold them back with great efforts; and so with a crouching step they get down with some degree of safety. And this, as I have said, is what happens in the spring.
