Graham:

Almost...

From Prairie Junction to Nisqually is the former American Lake Line, which before the Pt Defiance line was built, was the Grays Harbor Line (Lakewood/Lakewview to Aberdeen).

The Prairie line heads off to Tenino at the point known on the Lakewood sub as Prairie Junction. The old Prairie line currently ends just a little south of JBLM.

Working on my maps right now for an upcoming article.
