A system and method for collecting a core sample. The system includes an outer cylindrical tube, a drive head, a drive shoe, a cooling chamber housed inside the outer cylindrical tube, insulation, a core sample liner, an inlet tube, and outlet tube. The drive shoe further comprises a first, second, and third step, the first step configured to receive the insulation, the second step configured to receive the cooling chamber, the third step configured to receive the core sample liner, wherein the first step has a diameter larger than the second step and the second step has a diameter larger than the third step. The method includes drilling a hole in the ground with a drilling tool, enclosing a core sample by a core sample liner, freezing the core sample via a cooling liquid, retrieving the drilling tool at a surface of the ground, and removing the core sample encased in the core sample liner from the cooling chamber.
