Working on the Nazko Cone in Canada (Patreon)

Although this volcano has not erupted for ~7,000 years, it is still quite active. To the NW of the volcano are areas of travertine where CO2 gas bubbles out from the subsurface. You could almost call these two areas "low activity hot springs". 

As for why this volcano has its unusual modern appearance, its scoria has been largely stripped mined for industrial use.
