Desert Mountains can support a <l:6,104>city<e> which gains valuable protection in the rugged terrain. The terrain, however, slows movement and hinders the construction of <l:8,19>roads<e>. <l:8,3>Mines<e> are the only industry possible in mountains, although later they can be made more hospitable with <l:8,2>Hydroponic Farms<e>. <l:6,25>Rivers<e> greatly enhance this terrain.
