Alva

Alva lies right at the foot of the Ochil Hills. The Ochil Fault, movement of which gave rise to the steep southern scarp of the Ochils, coincides approximately with the old road along the base of the hills. The rock beneath the carse in this area is carboniferous. The town is situated on slightly higher ground than the surrounding carse, being on two overlapping alluvial fans, made up of material deposited by the Carnaughton Glen and Alva Glen burns. The spectacular Alva Glen cuts into the Ochils immediately north of the town. Alva Burn flows from the glen, through Alva, and into the River Devon. To the east of Alva Glen, and parallel to it, is the Silver Glen, where silver was mined at one time. A more recent attempt about 1 km to the south of Alva, the Glenochil Colliery, was not a success, and the site is now a prison.
