The ground under Dickinson
Missouri Plateau (unglaciated Great Plains). Weathered clay shales and sandstones, Pierre Shale and equivalents
The water table is deep, so basements rarely flood — but Pierre Shale is one of the most expansive substrates in North America. The risk here is mechanical, not hydraulic.

The mechanism here is the wet–dry cycle, and it peaks in the summer drought: clay shrinks hard from June to September, then the first heavy rain swells it back. Foundation cracks tend to appear at the ends of that swing, not during it.
Climate pattern for this physiographic region, not a forecast for your house and not from the soil survey. It answers a question homeowners actually ask: when does this show up.
