More yesterday-pics. The first ten or twelve or so are all taken in our back garden by a large downed tree and down the lane o’ raspberries.
It reminds me of one of those little molecular model-building kits.

Don't touch. Young Eastern redcedar leaves.

Alright, it’s time for a departure down sad lane. The next few pictures are from what I think might be an invasion of emerald ash borer (EAB) on what I think might be a green ash. EAB is decimating ashes across the Midwest, the eastern U.S. and parts of Canada.
Those squiggly lines are galleries, showing where the larvae (whatever type they may have been) fed.
This bark is really chewed up, obviously. You can see some of those larval feeding galleries and possibly exit holes (where the larvae, well, exited -- the EAB's exit holes are D-shaped, but they're also really small, about 1/8th of an inch, so it's difficult to tell if these meet that description). A lot of these could be holes from woodpeckers, too, which often feed on more distressed trees like this.
Adventitious shoot, that is, a shoot arising other than from an expected place. This is growing lower down on the trunk.This is a possible symptom of emerald ash borer.
There were also thin fissures up and down the length of the tree (another symptom) that I didn’t get any pictures of.
Many of the next pictures were taken around a ring of trees growing along the very steep hill overlooking a ravine on the other side of our house. Coming from the sad, infested ash tree, I had a bug’s-eye perspective in mind. I am the emerald ash borer, I said to myself. That’s almost as powerful and cool as “I am the lizard king.”
Pretend you're a little larva peering outside of your safe little hidey-hole under the bark for this one. Can larvae even see? Do they need to? Who cares, you can see in this imagining.
Looking at a tree...from inside a tree. Alright, not inside of it, obviously, but from a chunk of bark that had peeled away.

Next there was some extensive vine-age growing up many of the trees.

More Virginia creeper.
Virginia creeper holdfast?
I'm not sure what tree this is, but I love the greyish and coppery patches and the big lenticels.
I was obsessed with this little knot in this one tree, which was growing in the little ring with four or five others.
Mystery buds. They are red. Hey, maybe it's a WILD REDBUD.
Now that's just sad. This is the bark of the dreaded buckthorn (Rhamnus spp.), an invasive plant which is a big problem in Minnesota. It has really beautiful bark, though. In the last century, some species of buckthorn cultivated for ornamental use were still being planted in Minnesota. No more!
If I remember correctly, this little branch is from one of the buckthorns. Go, little lichen, go!
This is the underside of a Scots pine (Pinus sylvestris) limb. They have gorgeous orange shredding bark on the upper parts of the trunk and on the underside of limbs like this one.
