Summary

Willard Neal Georgia's Stone Mountain

Songbirds flock in great numbers to the gardens and groves around the foot of Stone Mountain, but there is little wild life up on the rock, itself. The soaring birds, such as vultures and hawks, are well acquainted with the updrafts which lift them skyward like elevators when the wind strikes the steep, smooth slopes, and they know where to find the best rides for each direction the wind blows.

Willard Neal Georgia's Stone Mountain

The dark gray color of Stone Mountain is not the granite, but the lichens which grow on practically all the weathered stone. Behaving like booby traps, these pioneer plants have tricked a number of venturesome climbers to their deaths. In a rain they absorb water and become quite slippery, almost as if the stone were coated with grease. In dry weather they crumble underfoot and the tiny particles roll like shot to start a hiker sliding. Walking on almost level ground can become an adventure.
The lichens are a pioneer plant form, a symbiotic relationship of fungi and algae.

Willard Neal Georgia's Stone Mountain

When such intense heat strikes granite the moisture between molecules is suddenly converted into steam, literally exploding the surface crystals, or flaking them off, as quarrymen say. Flakes fell away in a continuous stream. In 10 coarse, deep gouging, slivers as big as dinner plates and half an inch thick, sailed off the mountain like miniature red-hot flying saucers.
One thermo-jet torch could remove several tons of stone in a day; more than 48 men could do in a week with drills and wedges. Carving with it was a one-man job.
