That's definitely one of the few historic photos where extreme debarking is quite obvious and not ambiguous. Surely on up there in the upper echelons of intensity for historic tornadoes.

Here is another document talked about their rating issue. Damage viewer listed several houses near Blanchard "EF5 Candidate" and "trees nearby similar to EF5 damage of Bridge Creek and Andover". Tim Marshall also once mentioned that Chickasha may "straddle the line" and "the large section of asphalt scouring add confidence to EF5 intensity". But in the end, they still refuse to upgrade it.
In my personal opinion, i think Chickasha might have been a bit stronger than Goldsby. The ground scouring and tree damage was a little more intense in my opinion, although they both produced extremely intense tree damage. but both were absolutely into the EF5 range and deserve an EF5 rating

To be fair I'm kind of beginning to doubt the true intensity of the Rocksprings Tornado. For the rather rural nature of the tornado, there really isn't any photographic evidence confirming the area of "worst damage." Trees were denuded, homes were destroyed, and downtown businesses were severely damaged, but there is no photographic evidence that I've seen that make me think that this tornado was anything special.
Keep in mind that photographers from that time would usually ignore the areas of extreme damage as piles of debris or empty foundations wouldn't sell well. They also usually went for heavily-populated areas such as downtown instead of rural areas.

I mean, come on now. If you tear a John Deere in half, you gain automatic entry into the F5 club. Those are just the rules.
Personally, I remain unconvinced that the second Dunlap (Sunnyside) IN tornado would merit an EF5 rating. Much weaker tornadoes have scoured asphalt, for instance, yet the Sunnyside tornado apparently did not. Moreover, the “ground scouring” could very easily be related to precipitation and tire marks in a muddy area. Clearly, most of the leveled homes were relatively small, of CBS type, and not anchor-bolted properly. Debarking is relatively unremarkable. Incidentally, all these caveats also apply to the other “borderline” EF4/5 candidates on Palm Sunday ‘65. I think a number of the officially “sub-violent” tornadoes on Palm Sunday II were grossly underrated, including the Lake Como WI F1 and the Koontz Lake IN F3, but I have yet to see any convincing evidence of EF5-level damage in this outbreak, although the Lebanon–Sheridan IN F4 did some fairly impressive debris granulation. Singular instances of damage are not enough to warrant top-tier classification, in my view, considering all the variables at play and the considerable uncertainty involved in rating these “older” events. Studies by Thomas P. Grazulis and others have proven that even (E)F2 winds can hurl heavy vehicles and machinery for a few hundred yards at least. Debarking varies by species, ground scouring by soil type and disturbance, and so on.
Damage from the 1942 Capitol Hill OK tornado, the deadliest OKC tornado until 1999. It was given an F4 rating by Grazulis and the vehicle damage is extremely impressive. 35 people died in an area 2.3 miles long and up to 500 yards wide.

I’m rather surprised that no one has commented on the “pulverisation” of debris and shrubbery in this final last image. Every vestige of greenery seems to have been pulled from the ground, and the amount of dirt flung about seems to hint at genuine ground scouring, though one would need several high-resolution close-ups to be more certain. If my eyes are not mistaken, then this phenomenon would seem to suggest that the Capitol Hill OK tornado may have been far more violent than it is given credit for. Only the most intense tornadoes pulverise debris and shrubbery. Then again, the OKC area is notorious for some of the most violent tornadoes on record. Incidentally, there was also a mile-wide F4 tornado that struck Newcastle and Moore OK in April 1893 (I can’t recall the exact date listed in Significant Tornadoes, but I believe it occurred toward the end of the month).

Personally, I think the strongest tornado from Palm Sunday II may have been the Pittsfield OH F4. A cursory view of the available photographs at the bottom of this Web site suggests why. For instance, there is a photograph of the remains of the Congregational Church that shows clear debris granulation and even partial debarking of mature trees in the background, along with possible ground scouring. I still don’t think that this tornado shows clear evidence of EF5 damage, but it comes a bit closer than the rest of the EF5 candidates in the outbreak, in my view. I can’t post direct links to the photographs on the Web site, given that they are all copyrighted, so I am wondering if anyone else has a bunch of high-resolution photographs from Pittsfield.

Yeah, there are some clear similarities between the two, and it's long been speculated in both cases that the long duration of tornadic winds may have contributed to the totality of the destruction. Certainly gives the tornado plenty of time to grind the debris down into tiny chips and chunks.
What do you think is the strongest of the 1965 Palm Sunday tornadoes and what are some notable extreme damage it produced?

1903 Gainesville tornado is partly hiden by notorious 1936 Gainesville tornado in history though more than 100 were killed in the storm. It is in fact a very mysterious tornado since it is an F4 in GA in June with limited amounts of digital records.

1944 Appalachians tornado outbreak is also a fatal and mysterious event discussed less today. It is really strange to see long track violent tornadoes in mountainous areas in late June.

Just an absolutely textbook northwest flow tornado event. These types of events are really rare, and it's hard for me to come up with a northwestern flow tornado event with the magnitude of the one on June 23, 1944. June 2, 1998, is also another good analog, but nowhere near as severe.

A photo I have in my archives of the scene at Pinson, Tennessee after the F5 Tornado came in the middle of the night on March 11th, 1923. The supercell responsible for this tornado was very high-precipitation and took the city by complete surprise at around midnight. Tennessee has a knack for having deadly nighttime tornado events. In addition to this one, other famous and deadly nighttime tornadoes in Tennessee include the February 5, 2008, Castalian Springs Tornado, the May 9, 1933, Livingston, TN Tornado, and the March 3, 2020, Cookeville Tornado.

This was a very unusual tornado setup. The supercell responsible for the Gainesville Tornado was associated with a rather weak low-pressure system interacting with high moisture and instability. In other words, it was a Plains Tornado setup except with much more moisture, favoring more obscured storm mode. The tornado itself was preceded by heavy rain and the sun came out immediately after it had passed, suggesting the presence of a high precipitation, intense supercell thunderstorm interacting with high instability values. I have these photos from it in my archives:

Never seen a photograph from Pinson until now. The thing sounds incredibly violent.
Some interesting details about this event:
To quote the link below:
"Newspaper accounts make special mention of a teenage boy who, after impassible roads forced him to abandon his horse just two miles out, trekked six miles on foot, in pitch darkness through mud and driving rain, to the nearby city of Jackson to deliver news of the disaster and plead for help. His heroism likely brought aide to the stricken town hours before it would’ve otherwise come. Eighteen people died in Pinson, and another seventy were injured. Human remains were found up to a mile away. It was Tennessee’s only F5 until 1998."

Juliett do you think rochelle might have actually been stronger than Plainfield? rochelle produced very intense structural damage and overall probably produced more intense damage than plainfield

The year of 1913 in Nebraska is usually known for the catastrophic outbreak in March. However, 7 months later another violent tornado struck the state, the 10/9/1913 Broken Bow F4 tornado family. This family of tornadoes touched down in Custer County and moved 95 miles into Holt County where it dissipated. The tornado likely was most intense in Custer County. A sod house was destroyed, an entire farm was completely swept away with everything being ground into kindling wood, fence posts were lifted out of the ground and carried for miles, a dozen farmhouses were "wiped from the face of the earth," heavy iron farm machinery was mangled beyond recognition and water tanks were carried 5 miles.

This is getting me thinking, i wonder what the longest distance a vehicle has been thrown by a tornado

So, here's possibly the dumbest question in the history of this forum.

Is there any truth to the heresay that all of Indiana was put under a statewide tornado warning during the 74 superoutbreak?
