There is only one tree in the entire Machu Picchu structure. Hiram Bingham cleared all the trees out after he discovered Machu Picchu. The lone tree supposedly took root from an Inca weaver's weaving post that was left in the ground after he gave a weaving demonstration many years ago. The weaving post is part of the weaver's loom. Weavers would pound one or more posts into the ground and attach their yarn to or around the posts making a loom.
