Apparently not in the Cascades
The most recent eruptions of Mount Hood – the tallest peak in Oregon – took place about 220 years ago and 1,500 years ago, according to Professor Adam Kent of Oregon State University and Associate Professor Kari Cooper of University of California-Davis.
When I saw that article in the Bend (Oregon) Bulletin, I thought – bingo! – that eruption hit smack dab in the middle of the Dalton Minimum, a time of extremely low sunspot activity.
And when the accompanying chart showed that fully half of all volcanoes in the Cascade Range had erupted around the same time, well, it looked obvious that volcanic activity correlates with low sunspot activity.
But then I looked at the rest of the chart.
What about the Maunder Minimum?
According to Kent and Cooper’s chart, only two – maybe three – volcanoes erupted in the Cascade Range during the Maunder Minimum.
If low sunspot activity coincides with volcanic activity, shouldn’t even more volcanic activity have occurred during the Maunder Minimum than during the Dalton Minimum?
Worldwide, there were at least 90 major volcanic eruptions in 1660 alone, according climatologist Cliff Harris and meteorologist Randy Mann.

So why not in the Cascades? Did those other eruptions somehow relieve the pressure in the Cascades?
At this point, I do not have the answer. Perhaps one of my readers…..?
