Sand Mountain is a
sandstone plateau in northeastern
Alabama and (to a far lesser extent) northwestern
Georgia. It is part of the southern tip of the
Appalachian mountain chain. Geologically a continuation of
Walden Ridge, Sand Mountain is part of the
Cumberland Plateau, separated from the main portion of the plateau by the
Tennessee River and
Sequatchie Valley. The average elevation on Sand Mountain is around above sea level, compared to about in the surrounding area. This elevation leads to its having the coolest climate in the state of Alabama. The largest city on Sand Mountain is
Albertville, in Marshall County. As of the 2010 census, the population of the city was 21,160.
