Geography
The Ségala is deeply valleyed region lying between 200 m and 800 m between the valley of the Viaur and the valley of the Aveyron. The valleys are deep and wooded, while the summits and the plateau are dominated by pasture land used for the raising of high-quality beef.
Geology
The underlying rocks are schists which leads to acid soils. The soils are light and thin, and were unproductive before the opening of the railway with the Viaduc du Viaur, which allowed lime to be brought in. Liming neutralised the soil opening it up to agriculture.
