Can you help identify this tree?

[KHall]

I have a couple ideas, but still not sure. Any thoughts would be appreciated. It's in Oregon, USA, in the Willamette Valley.

Never seen one slabbed up that way before.  You might be onto some new health fad.  Fiber with full flavor.  :D

White Alder?, being a Texas forester limits my knowledge of your trees to a text book.

And I thought for a moment that it was the mythical bacon tree 🥴

I'm seeing two completely different trees. Red maple clump and a willow. Willow will turn yellow quickly and maple not so quick, more whitish, yellows over longer time.

[Texas Ranger]

OK, fruiting body appears to be willow.

i see maple bacon.  goes good on beans with onions and hickory smoke.

There is the oregon ash which is what I thought the first tree might be. I agree there are two and willow of some kind is a good guess for the second.

Catkins, bark, and form suggest white alder (Alnus rhombifolia). 

Can't tell me from here if the bacon is alder smoked.

Alder flowers are more like a birch, these flowers are willow and similar to aspens and cottonwoods.
