I don't think the 2010 Tyler Tornado was intense when it was inside the MN border. I believe most of the scouring and EF4 damage happened in the ND side.I haven't looked at past MN Tornado events much with the exception of Fergus Falls 1919, Fridley, and Comfrey-St. Peter 1998, so I'd have to go with the Albert Lea-Conger EF4 from 6/17/2010, the Parkers Prairie EF4 from 6/17/2010, and of course the Tyler ND-Doran MN EF4. I personally have doubts of Chandler, MN being rated EF5 today, and it didn't result in any scouring from the photographs that I have seen (I'm probably missing something), so here's pics from all four.

The damage it did to a Ford has to be some of the most impressive car damage from a tornado I've ever seen. The structure was mangled and splattered with scoured mud.

It's likely that the slow movement of the Tyler Tornado played a part in its exceptional intensity, but nevertheless I feel that Tyler was the strongest of the trio. If you were to ask me what the strongest tornado all time in MN history would be, it would definitely be Fergus Falls
Also, it's path through southern Illinois (and maybe Indiana, not entirely sure) was parallel to a major railroad track, this being in the days when railroads were the predominant means of transport also contributed to it being so deadly, what with the numerous communities that sprung up along railroads back in the day. It's the equivalent of a modern-day rain-wrapped and fast-moving EF5 wedge following an interstate highway or freeway corridor through a major city during rush hour.A lot of newspapers had the same famous photo of damage in West Frankfort in altered versions but here's the most HD one I could find

That's all that I managed to find from hours shifting through online archives of newspapers. Poor people in the path had no chance. One reason that made this tornado incredibly deadly was not only its incredible power, but the fact that it was partially obscured with low LCL heights, as shown by witnesses in Annapolis describing it as a "thick black fog cloud" with a tremendous roar, and not recognizable as an actual funnel at some points. Also, the tornado severed all telegraph communications to cities in the path so residents had no kind of warning of what was approaching until it was right there. The tornado happened to be on a trajectory where multiple large cities were in its path also, a worst-case-scenario
I find it very interesting how the rotational signature on the supercell responsible for the tornado was not impressive at all.Continued with 10 more pics:

Of note, the ground scouring from this thing in the field was 700 yards wide, only Jarrell has a wider instance of the like (around 800 yards or so).
2004 had quite a bit of underrated violent tornadoes, don't forget Harper, KS also happening. I think all the surveyors for these things had said they wish they could go back and give them F5 ratings, in hindsight. The La Plata controversy back in 2002 likely contributed to these things being underrated and overlooked.Concerning July 2004, I feel that the Roanoke Tornado was not far behind the intensity of the Marion Tornado. The intensity reached by both tornadoes was phenomal.
