From the discovery of gold in the Georgia Gold Belt in 1828, enough gold was mined in the area to cause a branch mint of the United States Mint to be located in Dahlonega, Georgia. The region also includes igneous intrusions of granite and diabase. [6] Marble and talc are other resources produced in the Blue Ridge in Georgia. [5]
The first statewide geologic map of Georgia was published in 1825. It was a 1:1,000,000 scale map of Georgia and Alabama published by Henry Schenck Tanner. [3] In 1849 W.T. Williams published the geological features for the state on a 1:120,000 scale map within George White's (1849) Statistics of the State of Georgia report. [4]
Prominent peaks of Spruce Mountain, north to south, are Horse Rock (4,536 ft; 1,383 m), Spruce Mountain Peak (4,586 ft; 1,398 m), Picea Benchmark (4,613 ft; 1,406 m), and Spruce Knob itself. Spruce Knob is the highest point in the eastern United States between the Adirondacks of New York and Mount Rogers (part of the Blue Ridge Mountains) in ...
Around 480 million years ago, geologic processes began that led to three distinct orogenic eras that created much of the surface structure seen in today's Appalachians. [ d ] During this period, mountains once reached elevations similar to those of the Alps and the Rockies before natural erosion occurred over the last 240 million years leading ...

This list of the Paleozoic life of Georgia contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Georgia and are between 541 and 252.17 million years of age.
Most of Georgia was dry land by the time of the Quaternary period. Local sea levels rose and fell significantly in time with the expansion and thawing of glaciers farther north in the continent. Georgia's terrestrial environments included forests and grasslands. These were home to creatures like mammoths, mastodons and giant ground sloths. [1]
Pottsville-capped Spruce Knob in West Virginia South of Mount Porte Crayon and Seneca Creek, the Appalachian structural front is less clearly unified. Pottsville-capped Spruce Mountain , south and east of Seneca Creek, continues the Allegheny Front's geology southward; [ 5 ] this ridge reaches an elevation of 4,863 feet (1,482 m) at Spruce Knob ...
