Popis:	A set of gravity observations was taken at 3- to 4-mile intervals along a traverse through the Canadian Cordillera close to the international border. The isostatic reduction and interpretation of these measurements indicate that compensation beneath the cordilleran massif is regional rather than local. Using the Vening-Meinesz tables, the values found for T (mean crustal thickness) and R (radius of regionally) were 30 km and 116 km, respectively. These values imply a mean crustal rigidity that is comparable in magnitude with values determined from seismology and from postglacial rebound.
