Yesterday, I day-hiked the Approach Trail from the Amicalola Lodge up to Springer and back. The net elevation change from the Lodge to Springer is about 1,200' (from 2,500' to 3,700'). I was wondering if anyone with a GPS or other device has calculated the gross ascent, taking into account the intervening ups and downs, e.g. Frosty Mountain, Woody Knob.
