Tunnel tree
Large tree in whose trunk a tunnel has been drilled
A tunnel tree is a large tree in whose trunk a tunnel has been drilled. This practice took place mainly at the end of the 19th and beginning of the 20th century in the west of the United States.[citation needed]
The tunnel allowed tourists to walk or drive through the tree with a car. The tunnels were bored to boost tourism.[1]
The tunnelling seriously damaged the health of the trees. As a result, some trees have fallen. Due to the harmful effects of hollowing out trees, the practice of creating tunnel trees has been abandoned.[2]
