Mt Adams really isn't that far east

Post by Chip Down » June 12th, 2021, 2:11 pm

It's often said that Mt Adams isn't in line with the rest of the cascade range, but check out the USGS map below (I added the yellow line). Compared to its three close neighbors, it's a bit to the east. But if you look at the range, it's not an aberration.

bonus factoid: Look how far Shasta is to the west. I never noticed that.

That does not appear to be a least-squares fit. :geek:

Slow day at the office, eh?
You know exactly what to do.
There's no need to be afraid.
Keep walking.

The fastest easiest way to analyze the data is just run a vertical (n/s) line through Adams, and see how it compares to other peaks. But yeah, it did occur to me that there would be alternative approaches that would establish a "cascade crest" line. Of course, no need to reinvent the wheel; I'm sure others have already done that.

Oh man, it's brutal. I love being funemployed, but I need more drizzly-day hobbies. Come November, I might actually...gasp...get a job.

I've heard it said that St. Helens is the outlier, not Adams.

You can go out here: https://en.wikipedia.org/wiki/List_of_Cascade_volcanoes and see the location of all the Cascade volcanoes.

Adams isn't even the farthest east in Washington (Goat Rocks and Glacier Peak). And Shasta is just about as far west as St Helen's.

Adams is by far the driest of the big volcanoes and I think this leads people to see it as east of the crest. It is in the rain shadow of MSH and Indian Heaven.

It is a slow day at the office.

Taking the 67 Cascade peaks above 8000 ft elevation, plotting their coordinates on a graph and producing a linear trendline creates a line that essentially connects Manning Park, BC in the north and Redding, CA in the south, crossing directly over Hood River, OR.

This is where the major peaks sit in relation to the average crest line:

Baker - 43 miles west
MSH - 38 west
Rainier - 23 west
McLoughlin - 11 west
Hood - 6 west
Jefferson - 5 west
Adams - 4 west
Three Sisters - 1-3 east
Shasta - 5 east
Bachelor - 7 east
Stuart - 11 east
Lassen - 49 east

So Adams really isn't that far east! In fact, it's actually west (but not by much).

Wow- Lassen is really dragging that average to the east. (Though, on second look, you've included 67 peaks, total, so maybe it's not that far out of line?).
Believe it or not, I barely ever ride a mountain bike.
