Nope, this is not the one in Oregon! Yet another NW peak with a not-so-creative-name, Mt. Washington is a popular beginners climb fairly close to home. This climb can be combined into a longer day with a traverse of nearby Mt. Ellinor, another popular Mazama route.
We have the option to either meet on evening of Friday, 7/6 for overnight camping at the Big Creek Campground or meet at entrance of that campground the morning of Saturday, 7/7. We can consolidate cars there (and some people may even camp there Friday night????) and then drive to the TH from there. It's about a 15-20 minute drive from there. With 8 people, we think it will take 3-4 hours to the summit and about that long back down.
