The Pioneer Cabin Tree is the most popular attraction at the Calaveras Big Trees park in California. Rushing floodwater weakened the trees roots, causing it to topple over.
The tree was one of a number of giant sequoias that was turned into a tunnel back in the 1800s. The tree, along with other giant sequoias, has drawn millions of visitors who drive through it each year.
