SUSANVILLE, Calif. -- Where the fire came through Blacks Mountain Experimental Forest last September, the ground is ash and the trees are charcoal. Black and gray are the colors, lightened only by small mounds of red dust at the base of some of the charred trunks -- the leavings of bark beetles -- and flecks of green where new growth pokes above the ash.
Through the tall, ravaged columns, however, a living pine forest is visible. And as visitors inspecting the fire damage walk toward the living forest, they come to an abrupt transition.
September's blaze was named the Cone Fire, for the hill where it was first thought to have begun. It burned 2,000 acres of Lassen National Forest, and 1,600 of those were in Blacks Mountain Experimental Forest, a 10,000-acre area within Lassen set up in 1934 for ecological study by the Forest Service.
When the Cone Fire swept through these woods it came to a patch of forest that was different from the rest, and stopped dead. What stopped the fire was an experimental plot that had been selectively logged to thin it, and had been burned in controlled fashion. The result was an open forest, much the way it might have been 500 years ago when regular forest fires swept through the high dry country, and no one tried to stop them.
