The number was 46 until 1975, and 47 until 1980.
Got out my 1976 copy of the WMG. It lists 46 (and the list is in the front of the book, not the back). Galehead and Bondcliff are omitted, and Wildcat "E" is listed rather than Wildcat "D".
The 1979 copy lists 47, adding Galehead, and still lists Wildcat "E". The penultimate paragraph of the "lists" section notes "Galehead, with a new measurement of 4024 ft. becomes a 4000 footer."
I did a trip in 1978 with an overnight at the Guyot shelter then did Bond and West Bond, did *not* go out to Bondcliff (why would I, it wasn't on the list
, stupid younger me) but then visited Galehead because it *was* on the list.
My next copy is the 1987, and that lists 48, including Galehead, Bondcliff, and Wildcat "E".
Didn't get another copy until 2007, and that has Wildcat "D" rather than "E" - when did they make that change?
The description of the Owl's Head path in that edition notes that "The AMC's Four Thousand Footer Committee will continue to recognize the knob where the well-beaten path currently ends as the official summit of Owl's Head."
Have they changed that? Didn't see anything in either the 2012 or 2017 copies to indicate they had. Any thing else I missed?
Is it the case that "most" folks that have "done the 4Ks" have done 48, including either Wildcat "E" or "D"? If that is the case, I think it is perfectly reasonable to say "we aren't changing the list anymore". It is also perfectly reasonable to make a change whenever new information becomes available. It isn't that big a deal in the grand scheme of things - we're just climbing hills here, not sending a probe to Neptune...
