Glacier Peak (known in the Sauk Indian dialect of Lushootseed as "Tda-ko-buh-ba" or "Takobia" ) is the most isolated of the five major stratovolcanoes (composite volcanoes) of the Cascade Volcanic Arc in Washington. Located in the Glacier Peak Wilderness, the volcano is visible from the west in Seattle, and from the north in the higher areas of such eastern suburbs of Vancouver as Coquitlam and Port Coquitlam. The volcano is the fourth tallest peak in Washington State, and not as much is known about it compared to other volcanoes in the area.
