Seasonal steam rising from Mount Baker is a reminder to residents that the picturesque mountain across the border is among the Cascade volcanoes.
The mountain range features a series of once-active volcanoes, but the smoking look isn91裸聊视频檛 cause for concern.
91裸聊视频淚t91裸聊视频檚 mostly hot water,91裸聊视频� explained Dante Canil a professor in the School of Earth and Ocean Sciences at the University of Victoria.
Baker is what would be called a dormant volcano, as it hasn91裸聊视频檛 erupted in a major way for about 10,000 years. It does have a magmatic system, as do others in the Cascades considered more active, such as Mount Rainier and Mount St. Helens.
Baker has vents 91裸聊视频� or fumaroles 91裸聊视频� that go down into the mountain.
Steam is usually a result of snow melt and other water getting into the magmatic system, which heats it well beyond its boiling point.

The nature of the conditions make it a bit seasonal, with the steam spotted and making headlines, most frequently in the spring.

Mount Baker has been quiet, but it could still erupt someday. The impact in Greater Victoria would be minimal.

With prevailing west to east winds, experts guess even ash fall would be minimal as the Cascades spread ash deposits mostly to the east.

There are other hazards to those volcanoes for people living close to them. When the snow cap melts during an eruption, it sends a flood of ash and mud, with the consistency of concrete, down the mountain at alarming speeds.
