Fascinating how Subalpine Larch going southward just ends "sharply" at the Teanaway Peaks. Something about different soils further south?
(It's the like the opposite of bear grass, which super prolific around Snoqualmie Pass, but ends sharply in the Alpine Lakes going northward - no reports north of Stevens Pass).

I was nowhere near close enough to identify which type of larch it was. I haven't encountered any around Hood, but I did look online and see it occurs in Oregon.

I have noticed this and been fascinated and curious why it doesn't seem to cross Hwy 2.

I've thought about where the westernmost larch strand could be (confirmed longitude of about -121.29165, but could there be other strands further west?), but not the southernmost! It looks like the latitude of the southernmost larch in the Earl strand is about 47.40577 and as far as I know that's the southernmost that I've heard of. There is, or perhaps was after the intense fires last summer, a lot of western larch in the Aix area. That area is the kind of place that I would think could support alpine larches, but probably doesn't. |
Here's the distribution shown on iNaturalist:
Of course that could include mid-identifications and planted ones.
The western most one listed there in Washington is at -121.79559 in Gifford Pinchot.
Several reports near Mt Aix. |
That looks a lot like western larch (Larix occidentalis) distribution, not Larix lyalliss; subalpine larch. These line up well with the dots:

Thanks for the inaturalist tip, Phil. I located the range map for the subalpine larch:

It is not shown on the map John posted, but subalpine larch continues west to Sprite Lake, where you will find a few scattered, small trees in the meadows.
