southern MN | Prairies of southern MN here too.
Typically we have strong rains in summer, and strong winds with frozen ground and quick snow melts in spring. So the water runs over the ground into the low spots and filters away there. Over the decades we've dealt with drain or working around these areas.
This past year, we had a wet fall, deep snow on top of unfrozen ground, and a very wet spring. The rain pattern was lots of 12 or 24 hour slow rains, soakers.
So the ground got water soaked into it slowwly but constantly. Over & over and over. The snow melt happened all winter long, slowly. Our hilltops got saturated. This formed rare water channels and pockets that we don't normally see.
So we have new, uncharted ground water up on the hills this spring & summer. It's a very different thing.
Frost boils are just pockets of water that keep poorer soils from settling down.
The different rainfall and snow melt has created a different soil groundwater attern, and new problems are showing up they rarely appear.
See it out in the fields too - places that weren't ever wet were wet for planting this spring.
The township gravel roads were horrible this year, only the last 2 weeks have they started settling down a bit, but damage done, lots of dirt poking out on any hill on any gravel road.
