Thanks for your comments.
I was sort of aware of the longer string of mountains you cited as being "Custer Ridge" in the olden days. I don't think such an appellation is appropriate now. The divide from Whatcom to Rahm is quite haphazard and it's hard to call it one "Ridge."
I should ask Harry Majors to answer this question.
Regarding the Mox Peaks, what I find lamer is the oft-used and quite pedantic Twin Spires. You'll find many "Twin Spires" in the world but only one Mox Peaks. So, I like Mox Peaks. Which came first (Mox or Twin Spires) has been debated in the past (Harry answered the question on page 2 in this thread) but general consensus at the moment is that Mox was the original appellation. Mox apparently means "twin" in Chinook jargon.
Having climbed both Mox Peaks I could put page(s) up for them on SP but I will not. Some peaks need to maintain their mysticsm. The word Mox strikes fear in the hearts of NW climbers. Why squelch those fears with SP pages? I hope no one ever does put up pages for them--even if and especially if they only make an "attempt" at summiting them.
No critique here, just random info. WRT the scope of 'Custer Ridge', I seem to recall Tabor and Crowder's 'Routes and Rocks in the Mt. Challenger Quadrangle' ( my copy's been missing for 30 years) may have referred to the entire mass of mountains north of Whatcom Pass as Custer Ridge as well. Becky affirms the reference in his "Range of Glaciers' where he names Mt. Redoubt and Mt. Spickard as the high points of Custer Ridge. If Beckey actually originated this usage, it's probably because of his obvious respect for Henry Custer. In any case, Custer did considerable tramping around on the divide which bears his name, and the best the Forest Service could come up with for geographical names in the area was the rather lame 'Mox Peaks' (twin spires).
