Here's three photos showing the Carboniferous White Limestone, Old Red Sandstone (Altar Stone), Carboniferous Black Coal and Carboniferous Pale Grit source area for these Stonehenge rocks.
Here's an arial photo showing the ~100 tons of 1/4 Carboniferous White Limestone Counterscarp (foreground left). The other ~300 tons of 'missing' Carboniferous White Limestone Counterscarp was moved, piled, and is Stonehenge Mound (background left). Rammed in the ditch circling Carboniferous White Limestone Stonehenge Mound is the ~65 tons of Carboniferous Black Coal and Carboniferous Pale Grit from the South Wales Coalfield area. Old Red Sandstone (Altar Stone) is in the ~middle of Stonehenge.
Here's a photo of the Carboniferous White Limestone Mound from the opposite direction, and a photo of the now-famous Lion head, Calf head, Man face (clockwise), and Eagle wings (centering) Heelstone Sculpture from the archway (its intended view). Rammed in the ditch circling the Tertiary Sandstone Heelstone is ~19 tons of Carboniferous White Limestone from the South Wales Coalfield area. Atkinson was right about this immediate backfilled ditch, unfortunately he failed to inspect the elder limestone fossils.
Here's a photo of Carboniferous Black (bituminous) Coal and a photo of Cretaceous White Chalk. The geologic outcrop at Stonehenge is Cretaceous White Chalk. If you can see the color difference between the rock in the first photo and the rock in the second photo, congratulations are in order. You are smarter than the Stonehenge 'experts' (see first post).
Totaling ~465 tons of rocks, these ~400 tons of Carboniferous White Limestone, ~32.5 tons of Carboniferous Black Coal and ~32.5 tons of black Carboniferous Pale Grit hauled to Stonehenge, from South Wales Coalfield, in the Stone Age, are the equivalent of ~46.5 ten ton diesel truck loads full of rocks, the equivalent of ~465 one ton pickup trucks full of rocks, the equivalent of ~18,600 fifty pound animal skins full of rocks, or the equivalent of ~37,200 twenty-five pound clay pots full of rocks.
