The Colorado Auvergne: a magical place with red cliffs of several sedimentary layers. The first layers date back more than 400 million years. The upper part of the cliff was created by a lava flow.
This ferruginous spring gushes out in a fountain itself set in a stone enclosure, making the place intriguing, all the more so as the effect is accentuated by the deposit of rust which has tinted the fountain red.
