A beloved centuries-old giant sequoia tree that wowed thousands of visitors who passed through a tunnel in its massive trunk was felled after a weekend storm brought flooding to California this weekend.

At Calaveras Big Trees State Park, this is the walk-through tree, a novelty thought up and carved through by unknown pioneers, shown Aug. 19, 1969.

Its trunk was hollowed out in the 1800s as a tourist attraction, but the tree managed to survive until this weekend.

Social media users reacted with shock and disappointment on hearing of the tree's demise.
