In 1953 a fire swept though several thousand acres of the Ossipee Mtns, from the interior slopes of Mt. Shaw up and over the Shaw-Mt. Flagg ridge and into Canaan Valley. Although I don’t know the original forest type (I suspect it was heavy to spruce) the fire burnt to the mineral soil which created the perfect seedbed for White Birch, which this unique forested area is predominantly now. In some spots the soil was so thin that bedrock was exposed and it supports little vegetation today. In the photo is a small spruce stump charred from the fire.
