Unfrozen water content and hydraulic conductivity data were obtained for an air‐free frozen Alaskan silt using a new form of an ice sandwich dilatometer/permeameter that was designed to allow control of effective stress in the granular matrix through appropriate adjustments of pressure in liquid surrounding a specimen confined as in a triaxial test apparatus. Experimental complications included rejuvenation of conductivity during prolonged periods of equilibrium (no flow) after each temperature step immediately followed by very slow but continuing decay, as if without limit. When a formula of the Brooks and Corey type was fitted to unfrozen water content data, hydraulic conductivities inferred from the formula parameter, through the model of Mualem, provided an acceptable description of observed conductivity values, as measured immediately after the equilibrium period.
