The place where the acropolis was entered was believed to have been overlooked by the mythical Meles when he carried the lion round his fortress to make it invulnerable; it was really a path opened by one of the landslips, which have reduced the sandstone cliff of the acropolis to a mere shell, and threaten to carry it altogether into the plain below.
The greater part of the Maremma now affords pasture to large herds of horses and half-wild cattle, but on the drier parts corn is grown, the people coming down from the hills to sow and to reap. The hill country just inland, especially near Volterra, has poor soil, largely clayey, and subject to landslips, but is rich in minerals.
The Lower Lias appears at intervals under the scarp of the basaltic plateaus, and contributes, as in Dorsetshire and Devonshire, to the formation of landslips along the coast.
They are liable to be suddenly swollen by rains, and floods and landslips often cause considerable damage.
Torrential rains caused a series of landslips, carrying away houses and breaking up the hill railway.
