The 100 miles of rolling mountain country between Mt Lassen to the south and Mt Shasta to the north, is rich with scenery and recreational opportunities. This "Intermountain Area" is a land shaped by volcanic activity, very different from any other part of California. Hot and cold springs, fumaroles, old lava flows and lava tubes invite exploration. River canyons cut the land and there is water everywhere, in springs, creeks, lakes and rivers.
