ROCK
It is mainly made of earth, rock and wood before modern day materials were used.
By definition, a narrow chasm with steep cliff walls is a canyon. Exceptionally narrow canyons are called "slot canyons".
This ancient great wall was actually built of wood, earth, grass, and three principal different types of stone: granite (magmatic rock), white marble (metamorphic rock) and and white stones (sedimentary rock, like sandstone and limestone). There wasn't always rock available, so they used earth and rubble that they pounded until it was hard. In other places the hills were so steep that oxen couldn't pull the carts of rock up to the building site, so the men themselves carried the rocks on their backs. In the desert, the wall was built using sand, pebbles and grass. Shi Huang Di became the first emperor of a united China and decided that the various walls needed to be fortified and joined together. He ordered thousands of watchtowers to be built 12 metres tall and 12 square metres at their base with 6-metre walls of granite joining them.
