The specific details of that drive — how long it took, what the roads were like, what Wally was thinking — are not documented in any source I have seen.

What is documented is the result of the drive: Jean Hilliard arrived at the Fosston hospital in a state that stunned the medical staff.

She was rigid.

Completely rigid.

Her limbs were frozen in the position they had taken when she collapsed — face-down, with her arms at her sides or slightly extended, her legs straight.

She could not be positioned on a stretcher normally.

She could not be undressed by peeling back layers of clothing the way you would undress an unconscious patient, because her clothing was partially frozen to her skin and to itself.
