On February 28, 1864, Mr. P. C. Gosset and Mr. B—— started from the village of Ardon (about mid-way between Sion and Martigny), to make the ascent of the Haut-de-Cry (9688 feet), with the guides J. J. Nance, F. Rebot, A. Bevard, and J. J. Bennen. They arrived within a few hundred feet of the summit before mid-day, and determined to complete the ascent by following the crest of a ridge leading towards the east. Before this could be done it was necessary to cross some steep snow; and, while passing this, an avalanche was unfortunately started. Bennen and Mr. B—— perished; the others happily escaped. The following narrative, from the pen of Mr. Gosset, illustrates, in a very impressive manner, the danger of traversing new-fallen snow at considerable inclinations:— “We had to go up a steep snow-field, about 800 feet high, as well as I remember. It was about 150 feet broad at the top, and 400 or 500 at the bottom. It was a sort of couloir on a large scale. During the ascent we sank about one foot deep at every step. Bennen did not seem to like the look of the snow very much. He asked the local guides whether avalanches ever came down this couloir, to which they answered that our position was perfectly safe. We had mounted on the northern side of the couloir, and having arrived at 150 feet from the top, we began crossing it on a horizontal curve, so as to gain the E. arête. The inflexion or dip of the couloir was slight, not above 25 feet, the inclination near 35°. We were walking in the following order:—Bevard, Nance, Bennen, myself, B., and Rebot. Having crossed over about three-quarters of the breadth of the couloir, the two leading men suddenly sank considerably above their waists. Bennen tightened the rope. The snow was too deep to think of getting out of the hole they had made, so they advanced one or two steps, dividing the snow with their bodies. Bennen turned round and told us he was afraid of starting an avalanche; we asked whether it would not be better to return and cross the couloir higher up. To this the three Ardon men opposed themselves; they mistook the proposed precaution for fear, and the two leading men continued their work. After three or four steps gained in the aforesaid manner, the snow became hard again. Bennen had not moved—he was evidently undecided what he should do; as soon, however, as he saw hard snow again, he advanced and crossed parallel to, but above, the furrow the Ardon men had made. Strange to say, the snow supported him. While he was passing I observed that the leader, Bevard, had ten or twelve feet of rope coiled round his shoulder. I of course at once told him to uncoil it and get on the arête, from which he was not more than fifteen feet distant. Bennen then told me to follow. I tried his steps, but sank up to my waist in the very first. So I went
