What would be a 5-needle pine on Mt. Hood?

Hello all. I just collected some seedlings of 5-needle pines up on Mt. Hood at around 3400 ft elevation, in a clear-cut among lots of larch seedlings coming up with them. Does anyone know what species of pine they might be? I’ve tried googling “5-needle pine species native to Oregon,” but have only gotten unhelpful/confusing results.
Thanks in advance!

Probably monticola but maybe lambertina or albicaulis.

Any pictures of the needles?

Potrebbe essere un pinus strobus

P. strobus (Eastern White Pine) is found on the eastern half of North America and is unlikely to be found on Mt. Hood.

Thanks nmhansen - took me awhile to figure out how to upload the photos.
I doubt it’s a sugar pine (lambertiana) based on the range being more confined to southern Oregon and CA. Western White Pine (monticola) or Whitebark (albicaulis) sound right distribution-wise. I would guess not whitebark because elevation was fairly low for whitebark, and the needles of the smaller one are rough when stroked from tip to base, consistent with western white pine. I had assumed that both the smaller and larger seedlings were the same species because they were right in the same place, and I figured the longer needle length on the bigger one just reflected the seedling/tree being older/bigger. BUT, when I stroked the needles of the larger one back from the tip, they were smooth, which would suggest that one might be a whitebark. These seedlings were everywhere in this clearcut, mixed in with larch growing everywhere as well. I just find it very unlikely that western white and whitebark pines would be growing in the same place like that, but the needles are definitely different … puzzling.


This is a pinus strobus.

It is a Western white pine (Pinus monticola)
