Good morning! What a FASCINATING thread! I didn't notice if anyone mentioned asking David Dilgard at the Everett Public Library's Northwest Room about these early SnoCo businesses/mines etc. Over the years, I've learned that if Dave doesn't know something about our county, he can usually suggest other places to search or folks to ask. The Northwest Room at the EPL is a major resource - we are so lucky to have EPL-NWR practically in our backyards! Regards to you all... Marge
