Cryostatic pressures in nonsorted circles (mud hummocks), Inuvik, Northwest Territories
Experiments were carried out during the 1967–1972 period in an attempt to measure cryostatic (frost-induced) pressures by means of soil pressure cells installed in nonsorted circles (mud hummocks) at Inuvik, N.W.T. Although slight soil pressure increases were measured in the hummocks during the free...
