Stock Photo: Landslide on the side of the Hancock Mountain Range in the Pemigewasset Wilderness of Lincoln, New Hampshire USA. Heavy rains from Tropical Storm Irene in 2011 caused a old landslide that was in the process of being natural regenerated to slide again. The natural process of regeneration must start all over. The new landslide looks to follow the track of the old one. This storm caused extensive damage along the East coast of the United States and the White Mountains, New Hampshire.
