It is said to have erupted many times, but the most famous eruption was on May 18, 1980, which took out most of the forest around it.
Mount saint helens eruption spewed how many tons of matter?
Mount Saint Helens wasn't a small or moderate eruption. It was huge. Read below (from Wikipedia): On March 20, 1980, Mount St. Helens experienced a magnitude 4.2 earthquake.[1] Steam venting started on March 27.[35] By the end of April, the north side of the mountain started to bulge.[36] With little warning, a second earthquake of magnitude 5.1 May 18 triggered a massive collapse of the north face of the mountain. It was the largest known debris avalanche in recorded history. The magma inside of St. Helens burst forth into a large-scale pyroclastic flow that flattened vegetation and buildings over 230 square miles (600 km²). On the Volcanic Explosivity Index scale, the eruption was rated a five (a Plinian eruption). The collapse of the northern flank of St. Helens mixed with ice, snow, and water to create lahars (volcanic mudflows). The lahars flowed many miles down the Toutle and Cowlitz Rivers, destroying bridges and lumber camps. A total of 3.9 million cubic yards (3.0 million m³) of material was transported 17 miles (27 km) south into the Columbia River by the mudflows.[37] For more than nine hours, a vigorous plume of ash erupted, eventually reaching 12 to 16 miles (20 to 27 km) above sea level.[38] The plume moved eastward at an average speed of 60 miles per hour (95 km/h), with ash reaching Idaho by noon. By about 5:30 p.m. on May 18, the vertical ash column declined in stature, and less severe outbursts continued through the night and for the next several days. The St. Helens May 18 eruption released 24 megatons of thermal energy;[39][40] it ejected more than 0.67 cubic miles (2.8 cubic km) of material.[25] The removal of the north side of the mountain reduced St. Helens' height by about 1,300 feet (400 m) and left a crater one to two miles (1.6 to 3.2 km) wide and 0.5 mile (800 m) deep, with its north end open in a huge breach. The eruption killed 57 people, nearly 7,000 big game animals (deer, elk, and bear), and an estimated 12 million fish from a hatchery.[6] It destroyed or extensively damaged over 200 homes, 185 miles (300 km) of highway and 15 miles (24 km) of railways.[6]

What are some of the physical features of Washington state?
Mt. Rainier is probably the most obvious feature. It is a large, geologically active volcano, and is admired from many vantage points in the state for its beauty. Some might argue that Mt. St. Helens is equally importnat - it did erupt in 1982, spewing volcanic ash for miles around.
