Number of P and S arrival-time observations used to compute the hypocenter location. Glaciers on Mount Hood retreated through the first half of the 20thcentury, advanced or at least slowed their retreat in the 1960s and 1970s, and have since returned to a pattern of retreat. A long dormant period ended around 1,500 years ago, meaning Mount Hood is not considered active. The Mount Hood forest is home to approximately 1,000mi (1,600km) of trails. Mauna Loa is the largest active volcano on the planet. steam vents, or fumaroles, near Crater Rock attest to heat below. Magma generated by the subduction process rises upward through the crust and feeds a line of active volcanoes that extends from northern California in the United States to southern British Columbia in Canada.
