We may look at them and think that they are just mountains that have grown over geological time, but they are more than that. In reality, a lot of them are volcanoes. The most popular one is Mount St. Helens. Mt. St. Helens is located in southwest Washington, just 50 miles northeast of Portland, Oregon.

With its stunning and incredible views from the peak, you also get a surreal feeling that is a little discomforting. Maybe it could be because Mt. St. Helens is very much still alive. Mt. St. Helens started to grow during the Pleistocene Epoch. It started with dacite and andesite eruptions that existed of hot pumice and ash. Large mudflows flowed down the volcano, which have become important pieces to the eruptive cycles of this volcano. Later, there was another eruptive period, along with the pyroclastic flows of hot pumice and ash, was dome growth. Mt. St. Helens has been one of the most active volcanoes, but has experienced long periods when it has been dormant as well. It was considered a composite volcano, which was a symmetrical cone with steep sides. Most composite volcanoes are known to have explosive eruptions, which could be very dangerous to life and property nearby. From 40,000 years go until its most dramatic eruption in May 1980, Mt. St. Helens continues to show us life still exists within it. Within the last 2000 years, Mt. St. Helens has “been more active... ... middle of paper ... ...html>.
