The Aigoual is a granitic mass, reaching to 5,140 feet, whereas the Roc de Malpertus, in the Mont Lozère group, rises to 5,520 feet, but this latter is far less suitable for meteorologic observation. Around the Aigoual erosion has formed a labyrinth of gorges and profound valleys, in the beds of which race torrents impatient to reach lower levels. From the side of Merueys, the Aigoual does not present by any means an imposing appearance. It is a domed green mass, on the top of which gleam white the walls of the Observatory. From the side of La Luzette it bears some resemblance to a huge antediluvian monster in a crouching posture with fore paws extended. On the south side the Aigoual is rugged and abrupt. Its precipices descend to great depths. The stream of the Claron there in a succession of falls drops to the depth of 3,000 feet in a very short distance. The Aigoual has two heads, one of these, La Fayède, looking towards the sun-bathed basin of the Rhône; the other, that of the Hort Dieu, the loftiest but the least picturesque. Between these is a coombe, watered by a thousand springs that ooze from the turf and nourish a rich vegetation. It is this coombe really which is the Garden of God, as the natives term it. On the one side the Aigoual rises out of mulberry and chestnut woods, torn and precipitous; on the other it is smooth and velvety, wooded only with distorted beech. It has been ravaged by the merciless axe of the peasant that has left it bald and desolate. From the summit a superb view is obtained of the tossed and torn ridges of schist mountain, some rounded, but furrowed like the face of one very aged, some starting up into peaks, some stretching out saw-like ridges, some flat-headed, according to the nature of the rock of which composed. To the north rises the Tarnon that passes by Florac, below which it enters the Tarn. A little to the north-east is the Signal de l'Hospitalet, and beyond Barre des Cévennes. The old Roman road ran over this latter col to penetrate into the heart of the Cévennes; it kept to the crest, commanding glorious views. The Aigoual should be ascended from Meyrueis, a little town half the population of which is Protestant. Near it, and on the way, is the Renaissance castle of Roquedols.
