Amicalola Mountain is the first summit on the AT Approach Trail. The ridge rises from near Dawsonville on its southwest flank to Nimblewill Gap not far from Springer Mountain at its northeast point. Its highest section is known as Frosty Mountain and was once the site of a Forest Service fire tower which has been disassembled and removed. All that remains of that tower are concrete footings partially hidden by vigorous undergrowth in the old clearing where it once stood. Best known as the ridge line that serves as the source of the stream that produces Amicalola Falls, it rises abruptly from a valley floor at roughly 1500 feet above sea level, offering an impressive forested face. The south facing slopes of Amicalola Mountain are extremely steep; deceptively so as they are covered in a fantastic array of hardwoods that hide what would appear as cliffs in a less temperate zone.
