Is it inside of city limits??? I don’t know.
I believe it’s called Mt Tabor, part of the Pacific Rim Volcanic line-up. It’s supposed to be extinct.
Key word: supposed.

Unless there are underground steam pipes... like NYC? Or an underground coal fire? Like a town we have in PA.

A geologist/volcanologist on television right after the Mt. St. Helens eruption:

There is no such thing as an ‘extinct’ volcano............

Years ago while in New Zealand we went to a town called Rotorua. It has volcanic steam vents all over the place and the smell of rotten eggs is powerful. Everywhere you look you see a buildup of sulfur crust on the vents they have set up. A truly amazing experience. But the upside is that they don't have to pay for heat...all the houses are hooked up to the volcanic steam.

New Zealand...volcanic. Japan...volcanic. Alaska...volcanic. West Coast of North America...volcanic.

Mt. Tabor is a small cinder cone in SE Portland, well within city limits. Back in early 1980, when Mt. Saint Helens was starting to show activity, some of us were thinking about burning a few tires at the top of Mt. Tabor early some morning, but we didn’t.

That's what I was thinking too ... a lot of big cities have centralized steam heating for DT buildings, since it keeps fuel trucks out of the Downtown

Otherwise, it's free, clean energy!

Mt. St.Helen’s was extinct too......;-)
