Tolkien's final First Age timeline

[Arvegil145]

I just want to add another thing about the Dwarves:

Probably that mountain afterwards known as Caraðras; though unless its awe-inspiring peak was magnified in legend, it was then loftier than in later ages. “Under” plainly means “under the shadow of”; for there were as yet no Dwarves in those mountains, and the mines of Moria had not been begun. Neither, fortunately for the Eldar, had the Orks of Morgoth yet reached those regions.

- NoME, 'Silvan Elves & Silvan Elvish', Text 1, footnote 3, p. 357


Not sure if this quote implies that the Dwarves did not awake yet (IMO the most natural reading) or that Durin was still gathering his folk (but 800 years, in the current timeline, is a long time to be doing that).



P.S. Also, Curufin is the 4th son in Tolkien's latest conception.



EDIT: Nevermind, I see you included the comment on the 'no Dwarves under Caradhras' in the timeline - but my question still stands: how did you reconcile it with the very early Awakening of the Dwarves?
