The Goldyke series consists of very shallow, well drained soils that formed in residuum and colluvium derived from volcanic rocks.
Goldyke soils are on hills and pediments.
Slopes are 2 to 50 percent. The soil surface is covered with 30 percent angular rhyolite pebbles. Depth to bedrock - 4 to 10 inches to a paralithic contact. Hard bedrock is within 40 inches. Calcium carbonate equivalent - 1 to 5 percent.
