Nearly One Year After Castle Fire Began, Smoldering Giant Sequoia Found In National Forest

Scientists have discovered a giant sequoia still smoldering in California’s Sequoia national forest, months after wildfires tore through the region last August.

The tree was found, charred but still standing, by researchers in the lower part of the national forest this week. While turning down a sharp switchback on the trail, a member of Sequoia’s fire ecology and research team spotted a plume of smoke in the ravine below. Using a long camera lens, the team tracked the smoke to a single giant sequoia, standing in the burn area from last year’s Castle fire. The enormous tree, which has probably stood for hundreds if not thousands of years, looked like a chimney spouting smoke in the middle of the blackened forest.

In August, lighting struck deep in Sequoia national forest. The resulting Castle fire spread into areas of the Giant Sequoia national monument, home to trees that have stood for over 2,000 years, including “General Sherman”, the largest tree on earth. For weeks the Castle fire burned through 150,000 acres of land, before crews managed to contain the blaze in late December. Now researchers know that while the flames disappeared, some embers remained smoldering throughout the winter. The fire inside the tree discovered this week was sheltered inside the tree for months, even through the winter’s rain and snowfall.

Mike Theune, fire information officer for Sequoia and Kings Canyon national parks, said it was not wholly unusual for some patches of ember to remain burning months after a fire dies down. The inside of a tree, like the interior of a wood-burning stove, can provide an oxygen-rich shelter for a fire to survive. However, the fact that a Sequoia is still giving off smoke after an entire winter of rain and snow could be testament to California’s exceptionally dry winter: after precious little snowfall over the last two winters, most of the state is entering extreme drought conditions.
