Awesome! I didn't seen the native ones in Western WA- I've only seen blackberries there when I was on the WA coast. These are in SW OR so I Imagine they may be very similar :)
Yeah, the blackberries are all over. The black raspberries are a bit harder to find but I really love them. First time I found out about them was when I was out on a solo backpacking hike in the Olympic Mountains and I came across a large patch on the trail that no one was eating. After I setup camp I hiked all the way back to the patch so I could get a bunch--made for a great desert that day! :)

Wow what a large distribution range! Its nice that we can both enjoy these yummy raspberries.. haha I bet that they were worth the hike!
They love to grow on forest edges here so as soon as my trees get a bit bigger I plan to plant a bunch all over. Can't wait to get to harvest them at my own place! :)
Cool! Maybe collect some seeds from your wildcrafting this fall to stratify and in a few years when the trees get bigger you'll have some strong vines to transplant :)
