In 2013, the Rim Fire burned over 250,000 acres of forest in the Sierra Nevada mountains. The fire spread into Yosemite National Park, and burned right up to Tuolomne Grove, one of the park’s three ancient groves of Giant Sequoias. Thanks to some backburning efforts to clear out the brush, and mild winds on those days, all of the big trees were spared. Many of their younger neighbors, however, were not so fortunate. On my visit this spring, I was struck by the contrast of budding flowers and new growth against this charred landscape.
