Some photos from our security camera today showing the variation in visibility. The tree behind the neighborβs house that disappears is about 100 feet away.
@ehurtley Well, it is 2020, and it is a not utterly extinct volcano so consider it Shroedinger's Mountain?
(But the earth would have shook, etc.)
Here are some views from not-the-security-camera from a few days ago when the smoke was just rolling in - you can see the valley beyond. Definitely can't see that now. And even these pictures are "reduced visibility" from normal.
