Ironwood Basin, Wyoming Territory, 1889. While her neighbors stacked cordwood and prepared for another brutal winter of endless wood-splitting, widow Elizabeth Mercer was building something they'd never seen before—a massive mound of earth and sod against her cabin's north wall.
They called it a burial mound. They said she was risking her daughter's life on a foolish experiment. They predicted the earth would freeze solid and pull heat OUT of her cabin instead of holding it in.
But Elizabeth understood something about physics that her neighbors didn't: the earth eight feet down never freezes. And if she built enough thermal mass against her cabin wall, it would store the heat from her modest cooking fire and radiate it back through the long frozen nights.
When January 1890 brought temperatures of -43°F and winds that killed a man a mile from safety, Elizabeth Mercer's chimney barely smoked. While her neighbors burned sixteen cords of wood in six days and still slept in their coats, Elizabeth and nine-year-old Hannah stayed comfortable at 48° inside their cabin—burning less wood in a day than others burned in an hour.
The earth berm worked exactly as she'd calculated. And when the cold finally broke, the same neighbors who'd mocked her came asking one question: "Will you teach us?"
This is the true story of frontier ingenuity, a mother's determination to protect her daughter, and the physics of thermal mass that would eventually spread across three counties—saving lives and transforming how homesteaders survived the Wyoming winter.
