Round House facilities north of Everett, WA

[Road Fan]

Here is a head scratcher.

Last year Trains ran an issue about round houses and mentioned that they were usually spaced around 100 miles apart.

In Everett, Washington, the Great Northern had a roundhouse, the Milwuakee Road had a turntable but no roundhouse and the Northern Pacific had an engine house for 2 locomotives and I believe they turned their locomotives on a wye.  But each of these class 1's had lines north to the Canadian border and it made me wonder if they had built roundhouse facilities north of Everett, like Bellingham or Sedro-Woolley, or Snohomish.

Did the Milwaukee Road have any roundhouse facilities on the Olympic penninsula for its disconnected barge lines, like Port Angeles, or Port Townsend?

Thanks,
