There seems to be good evidence, consistent evidence, that this event is what formed the Carolina Bays.

And was the event that killed off many of the megafauna, like the mastodons.

2200 degrees C????? Wow,

That is a good question. There must have been a major die-off associated with such a large event.

I worked (soil investigations) in Carolina Bays for 11 years, and I am completely convinced that Carolina Bays do not result from bolide impact. They are hydrologic in nature.

On Alaska's north slope, there are elliptical ponds that are very similar to Carolina Bays. These are Holocene (post-Younger-Dryas) in age, and in fact, are continuing to form and enlarge even now. That area was covered with ice during the Younger Dryas period. These ponds form as a result of emergent groundater freezing and expanding during the winter, which pushes soil away from the center of the body. I suspect Carolina Bays formed similarly.
