I learned something today: "The giant sequoias in two of the three sequoia sites threatened by the Rim fire, the Tuolumne and Merced groves, some of which date back more than 2,000 years, have their own retardant: a rust-colored, fire-resistant bark that can grow several feet thick. While the tree trunks repel flames, the cones absorb the heat to disperse seeds needed for reproduction." Nature is amazing.
