Greetings, and welcome to BT.
Congrats on being one of the few first-timers to have a filled in profile <g>
If you use the Search function, there are several threads on digging out a crawlspace into a basement. Some of those threads might even be helpful <g>.
I would think that MN would have a frost depth requirement of 42" or 48" or so, which would be a pretty good-sized c/s. My understanding was that's why most houses in the area have basements, as the extra few feet of digging did not add that much to the project.

CAP,
Many really old buildings still standing in cold climates with foundations (still very well intact) resting on soil....Makes one wonder why we have to dig so deep to satisfy code.

Makes one wonder why we have to dig so deep to satisfy code.
Well, "code" is a rather inflexible thing, which tends to want "satisfying" whether needfull or not.
There is a factor of digging into "undisturbed" soil for "best practice" in creating a foundation, so building a uniform foundation in a "walk out," for example, would necessitate a rather deep foundation wall.
There's that innate conservitive/traditional building thing of " 'round here, e'ery place has basements," too.
Up around Dallas, there are parts of town where the Austin chalk is only 2-3' down, with a hard layer of blue shale under that. That makes for bad pool installs, and worse basement conditions. Using slab foundations makes a certain amount of sense there. In my part of Texas, down in the Brazos river valley, there's no "bearing soil" closer than 300', excellent digging conditions. But, almost no houses have basements--more tradition than sense. An earth-sheltered space under a house would have great utility in my climate.
Go figure.Occupational hazard of my occupation not being around (sorry Bubba)
