Not promising much precision in diagnosing specific agents affecting tree health from a photo, but I'm always ready to make a guess whether I know anything or not. When I was at U. Maine, one of the professors noted that science had not really arrived at a firm reason why trees die. Not referring to death from disease, insects, wind, fire, but just running out of life. Maybe it's similar to why there's a cap on human lifespan, cell replication gets sloppy and bad things result (simplification, but not irrelevant.)

When we lived in NNJ, it was easily noted that those caterpillars ate the white oak group first, then the reds, then everything else but ash. Have not noticed that white-over-red preference in Maine, though the fact that Maine has hundreds of red oaks for every white probably mutes the gypsies' priorities. Lots of reasons for oaks (or any species) to show that symptom, and weakness due to repeated defoliation/refoliation certainly could be a factor. If the non-leafed-out branches are in the main crown and receive good sunlight, the cause is likely some outside agent like gypsy moth or some disease. If the bare branches are within the crown/shade, it could be natural pruning, though white oak doesn't prune itself nearly as efficiently as red.

Not for much of NNE. And sun hasn't been all that abundant.

Usually EAB has infested a tree for a couple years before symptoms become visible, after which comes the quick death you saw. Apparently there is a very small minority of ash that exhibit resistance/tolerance for EAB, so I don't think the species group will go extinct, but will probably be gone as a significant component of the forest. Hillerich & Bradsby can switch to maple. Indigenous people in Maine and the Maritimes, for whom brown ash and the products made from it are important cultural facets, have no plan B.

I've read that oaks can harbor the chestnut blight fungus without taking damage; hence the inoculum remains in the forest waiting for its real food. Tough roots for sure! On the state lot (gifted by Gov. Baxter's nephew in 1969) near Merrymeeting Bay in Topsham, there are several American chestnuts. A white pine plantation was established in 1959 on 15 acres that earlier had been a market garden for about 20 years. We thinned the plantation early in 1989, and that fall I saw a 5' tall American chestnut growing in a skid trail. After 50 years (at least) under a plow layer, the roots still had sufficient vigor to sprout 5 feet in one growing season. 22 years later the tree was 11" diameter and over 50 feet tall, but now it's been blighted - dead above 15' and soon down to the root collar as well. Welcome to the regulated world of gas cans. they are designed to prevent you from catching on fire from spilled gas. and they suck And the irony is that I've spilled far more gas using the crummy thing that I ever did with the old "unsafe" ones. They're evidently designed so that one needs to employ both hands to use them (unless one unscrews the entire spout, which I'm tempted to do.)

Aspens showing some green at home, sugar maples in Augusta in full flower - looks like a good seed year for them (assuming tomorrow morning's freeze doesn't hit too hard.)

Agreed. The gray fur sprouts greenies.

Maybe -depends on lawn size. 32 yards will put 2" on 5,000 sq.ft.

Watched a short video on FB of Small's Falls, headwaters of the Sandy River, up towards Rangeley. Roaring in good shape, and still a significant amount of snowpack there. Going fast, but should keep waters fairly high for a few more days.

Some near-green on the south-facing field across from the house. Our lawn was fully snow-covered 3 days ago, so still brown (with about 99% fewer molehills than last year - yay.) Aspen catkins full length - at a distance look like mud-colored foliage. Wood frogs began "quacking" last evening, along with a few peepers.

That proves that "scents sense" can vary hugely. I find the aroma of both foliage and wood to be quite pleasant, though eastern redcedar is even better. I'm no fan of some of the weird arborvitae cultivars sold by the nurseries, but as a forest tree (Northern white cedar) it's a critical component of deer wintering areas and makes great shingles, too. (It's also the siding on our house - 3-sided "logs" that add 3-5" insulation.)

On the south side of the house, maybe.

I think parts of our lawn will become visible this time next...month.

21 years ago we had 2-3" qpf of ZR with some IP in central Maine, and some folks went 3-4 weeks without power, including the VP of Central Maine Power. Signs of that disaster are still visible if one knows what to look for.

Just checked out that site. 2/16/43 was 1/-43, quite the span. Their -35 on 2/17 was probably a 7:01 AM reading.

Certainly incongruous for PWM itself, not so much for the general area. In addition to the -37 at CON, Bridgton - 30 miles NW of PWM - also had -39. Gardiner, 50 miles to the NE, had -35. However, LEW, 30 miles N from PWM, only got down to -21, and the usually colder Farmington had -28. Their all time low is also -39, in Jan. 1994 (thanks, Pinatubo) on a morning when PWM was -10.

I'm not sure there are any year-round homes above 2000' in Maine - maybe in Rangeley, and if so, only marginally higher. Nobody's even close to 3500. In our almost 10 winters in Ft. Kent, we lived in 3 different spots, 2 in town at about 520' and the 3rd 4 miles to the sw at about the same elev as FVE. All 10 mornings with temps 35-47 below during those winters came at the lower spots. Those 2 sites averaged over 5 mornings/winter at -30 or colder, while the back settlement had only 1.5. WCI records depend, of course, on where observations are being taken. With the exception of MWN, those places usually are not the spots where the lowest chills have occurred. (As you infer in the above post) The state record low temp set in 2009 was at Big Black River, near the St.-Pamphile border crossing, at about 900'. However, I think that Estcourt Station, at 700', may actually get colder, but there's no official obs there. (Maine's coldest WCI is certainly atop Katahdin, 1000' lower than MWN but also 115 miles closer to the North Pole. And Governor Baxter's deeds of trust would probably be violated by having permanent wx instruments there.) C'est la vie.

Revisiting this - Clayton Lake lies in a broad valley at 1000' elev, about 400' higher than CAR. Clayton was -31 that morning, and given the full mixing, was probably at least as windy. I doubt they recorded wind speeds, but -31 at 20 mph converts to WCI of -62. Another revisit, that -85 (old scale) I mentioned in an earlier post. CAR temp was -20 at the time I heard that WCI from the radio, and that would require wind speeds in the low 40s. It was indeed very windy - the gauge on the lee shore of Portage Lake, about 20 miles west from CAR, was wiggling above/below 30 - but the low 40s had to be a gust. We spent that day in the woods another 10-12 miles west of Portage, and sustained 40+ would've had us dodging from crashing spruce trees the whole time. Mid 20s is more likely, for WCI (new scale) around -50, so not a contender.

Same for me. Not a wind chill situation, but when I handle firewood (outdoors) barehanded at +20, it feels cold. At -20 it feels painful.

PWM's coldest (midnight obs, so those 1/17 and 1/18 lows are 2 different mornings.): -39 2/16/1943 -31 2/15/1943 (My earlier -32 was an error.) -26 1/19/1971 -25 2/3/1971 -22 2/2/1961 -22 2/13/1967 -22 1/17/1971 -22 1/18/1971 4 @ -21: 1/24/48 to 1/20/1971. (No surprise that Jan 1971 is their coldest month on record.) I'm 99.9% sure that no other coastal site in the lower 48 has gotten colder than that -39. Even in AK, I think one would need to go north of the Aleutian Peninsula to find a colder morning.

I suspect this was a Northeast-based cold wave. The winds never quit during the coldest days (Jan 14-15), suggesting backside winds from a strong LP. Many record low maxima were measured during those two days. Seeing all the Jan 1985 WCI records reminds me that NNE missed the worst of that huge polar dome, catching only the fringes. Lows for that month in N. Maine were in the -20 neighborhood, modest for that area. However, we never sniffed 32; most locales had month's "warmest" in the mid - or even low - twenties. Dendrite's links included the brief but shockingly cold Feb 1943 blast. The cold for that one was centered well south of places like PQI. NYC touched -8, their 3rd coldest morning on record and 6° colder than anything since, and PWM - a stone's throw from salt water - reached an amazing -39, probably in flat calm. Their coldest WCI for that period would more likely have been the evening before. After a subzero afternoon (about -5, though the day's high was -2 at 12:01 AM) the temp plunged to -32 at 11:59 PM. Their 3rd coldest day was -26, in Jan 1971.

Also the state's highest point, not surprisingly. On a visit there 10-12 years back, I noted a hardwood forest more typical of NNJ, or even CT - altitude/latitude mix. I'm still not impressed with that "record" for Maine. Given the dozens of -40 or colder readings, it would be surprising if not a single one had even the 5 mph breeze that would kick WCI colder than -52. Van Buren, former holder of the state record at -48 (in 1925 - almost certainly no wind data), has had mornings -44 to -47 on 4 days 1984 onward - 1/22/84 -47; 1/11/95 -47; 1/16/09 -44; 1/26/09 -45. Fort Kent had -42 on 1/14/57 (maybe no wind data, either) and -30 on CAR's -52 morning. Clayton Lake, 70 miles WSW from CAR, dropped to -31 on 1/18/82 and probably was just as windy as CAR.

There were 4 in the party, and one was lost in a crevasse at relatively low elevation prior to the windstorm. The others continued, and all 3 survived. I can't remember if they retained all fingers and toes. (I read the book during the mid 1970s.)

Many years ago I read a book called Minus 148 (old scale, obviously), about an attempted winter ascent of Denali during which the climbers were pinned for days by very strong winds. Don Sheldon, the famed Denali-region bush pilot, flew to the mountain during the winds to check on those men, and he recounted a near hover above the same spot while his airspeed indicator was at 140 knots.

Thanks for the link - a fun read. According to the article, Jan. 8, 1968 had a spell with temps running -38 to -46 and winds averaging 92 mph. What's the WCI for -46/92? About -110? The comment about eyes frozen shut reminds me of what I called "walk backwards days" when I lived in N. Maine. These had temps double-digits below zero and very strong winds. When one was facing to windward, a gust would make the eyes water and the first blink froze the lids together, at which point one had to turn away and cover the eyes with (protected) hands until things thawed. There was maybe 4-5 such days in my 10 years there.
