The Pioneer Cabin Tree was located in Calaveras Big Trees State Park near Sacramento, California. The tunnel was cut to create a tourist attraction. The tree was estimated to be more than 1,000 years old. Thousands of visitors came to see it every year. Now the fallen tree will likely be left in place to decompose, or decay.
The storm that knocked down the tree was one of the biggest to hit California and Nevada in a decade. It caused widespread flooding and mudslides across the region. More than 1,300 people were evacuated from their homes.
