So, I mentioned the 4/30/36 mini-outbreak a few days ago, and that sent me down the rabbit hole a little bit. Ended up plotting ~100 damage points to put together a map and it's pretty interesting. It was hard to tell precisely what happened in a few spots because this event was a pretty complex blend of tornadoes + downbursts that spread over up to a mile and a half at some points, but this is probably pretty close to the final version:
A closer view of the Estherville-Fairmont tornadoes:
The Milford, IA F4 was almost exactly 20 miles long (though it may have started up to 10 miles further WSW - still trying to confirm), maxed out at right around a mile wide and killed two people, as you can see. The Fairmont, MN F4 was ~49.5 miles long and about three-quarters of a mile wide. It killed at least four people, though there's conflicting info on a fifth person possibly dying as well.
There were also a couple of other short-lived F2s that I didn't get around to adding yet. I also found another apparently undocumented tornado southwest of Swea City (you can see the general location because I forgot to hide one of the damage points). It seems to have been a pretty short path from what I could find, affecting only a couple of farms, but some of the damage sounds fairly impressive.
Anywho, I'm planning on doing something on this event at some point, but in the meantime here are a few photos. The second victim of the Milford-Okoboji-Terrace Park F4 died in the barn here (foreground):
The farm owner's brother lived next door and his entire farmstead was blown away, but thankfully the familytree had noticed the tornado coming (it was mid-afternoon and the tornado was reportedly quite visible +
extremely loud) and fled in their vehicle:
Some more destruction from the Milford + Terrace Park areas:
Aerial shot from very near the end of the path, where it took an abrupt rightward turn through Terrace Park:
Farms destroyed south of Fairmont, MN by the second F4:
Photo says "2-ton storm victim" but I haven't found out exactly what it is yet - looks like some kinda trailer?
Near the end of the path, the tornado destroyed most of the fairground on the north side of Blue Earth:
