Rh the Allier is also a cañon, but they are as unlike as is a blonde beauty to one who is dark. They are both superb, but in manner totally different The Allier runs through rough basalt and crystalline rocks; the Ardèche flows between bluffs of limestone. The latter can be descended in a boat, the Allier cannot. The Allier looks north—the colouring, the vegetation, the climate are northern; the Ardèche in every one of these particulars is southern. The Ardèche has cut its way through a level plateau; the Allier flows between ranges of mountains. The cañon of the Ardèche is a street; the defile of the Allier is a lane. We cannot seek the Ardèche in the height of summer; it is just then when we would refresh in the cool draughts and the blue shadows of the Allier.

The chasm of this latter river has been formed at the point of contact of the lava with the granite. The volcanoes of Le Velay poured forth their molten floods which beat against the granitic mass of the Margeride, and the lava in cooling may have shrunk and cracked and so allowed the river an opportunity of escaping into the plain. In places it has cut through granite and schist. It had cut this channel before the volcanic vents opened. What these latter did was to deposit what they threw out in the trough of the Allier, and force that stream to renew its work of excavation; in the latter part of its course the ravine is cut through lava.
