History of Surduc

Vertical deepening of the valleys is relatively high, determined by geological structure (layers consisting of sandstones, clays, marls, conglomerates etc.). Vertical deepening is accompanied by an active torrential erosion, mitigated or stabilized by the level of afforestation. The commune is crossed by three major subunits of relief: Șimișna-Gârbou Hills, Prisnel Peak and Almaș-Agrij Depression, all running across the Someș Corridor. This leads to a very pronounced transition for relief and other geographic components, giving a note of specificity to geographical area of the commune
