Conifer IDs

The purpose of this forum is to help people identify things they've seen while out hiking: wildflowers, trees, birds, insects, small animals, animal tracks, even geographical features like buttes or streams

The arboretum next to the zoo has signs identifying different trees. They have an artificially large diversity. Good place to go if you want to learn tree types.

Great, I need all the signs I can find. And my hat is off to those of you who can ID from bark.

Anyhow, here's one sign.

Which I now realize on preview can't be read, so here's an enlargement:

And the tree to the left, Limber Pine.

And the tree to the right, Bristlecone Pine.

Most of the Bristlecones in this grove had very little bark.

In general, I've found the bark of large, mature trees to be super confusing. Good on you all.
I keep making protein shakes but they always turn out like margaritas.

New set, Lamberson Spur on Hood. John, want to check these for me? 8-)

Mountain hemlock

and then growing higher up

stripes on top and bottom = subalpine fir

larch!! (too easy, I know, but exciting to find them)

I think these are Engelmann spruce?

cones: western hemlock on left, but the brighter ones with the pointed/flat scales are Engelmann?

2 needle pine = lodgepole

3 conifers: (L-R) the lodgepole pine, a grand fir, and then WTF - mystery pine with striped needles

Mystery pine - needles are super long, is this a ponderosa? it was earlier in the day, so lower down

The treeline up at 6500 ft was all whitebark pine, and the krumholtz mountain hemlock high on Polallie Ridge turned into Pacific Silver Fir as we went down, but by then I'd stopped taking pictures of all the trees because we had a schedule to keep. ;)
Will hike off trail for fun.

I think you're correct on all except the "western hemlock" cone is, I believe, mountain hemlock (too many rows of scales for w. hemlock); also the mystery pine looks more like western white pine - can't see the needle bunches clearly, but there should be five per cluster.
