I just realized that I can get a Multnomah County library card even as a Washington County resident which gives access to the entire Oregonian archives, so I'm definitely going to spend a lot of time looking a bunch of events. Here's December 1892, when 29" of snow fell in a 6 day period with 24" of that in two days. And then another 30"+ in late January/early February.
