Mariners Player As A Volcano
The South Sister rises prominently within a crowded volcanic field, and it’s known to be relatively young. A few years ago, there were signs of unrest, as geoscientists detected uplift just west of the peak. It was unknown whether the area might be on the verge of a destructive eruption. However, the rate of uplift has since slowed down, such that now it’s hardly noticeable. Though the area is closely monitored, there exists no present threat of activity.
