The tree's exact age and height were not immediately available, but sequoias can measure their ages in millennia and grow taller than 100 yards, or more than the length of a football field. They are the tallest trees in the world, according to Mario D. Vaden, a tree expert who has worked with the Save the Redwoods League in California.
Photos show the sequoia splintered on impact. If the question is whether a tree falling in the forest makes a noise, this one probably did.
The Pioneer Cabin Tree was in Calaveras Big Trees State Park, 100 miles southeast of Sacramento. Its trunk was hollowed out in the 1880s to compete with similar trees in Yosemite National Park, perhaps 50 miles further to the southeast, as the crow flies.
At first, only hikers passed through the Pioneer Cabin Tree. Then cars, once they were invented, were allowed. But more recently, passage was again limited to pedestrians only.
