The Snowbird Tectonic Zone (STZ) is a ca. 2800 km geophysically defined lineament that bisects the western Churchill Province, divided it into the northwestern Rae and southeastern Hearne domain (or subprovinces). The easternmost Rae domain is underlain by an extensive (>20,000 km2) area of high P granulite interpreted to be representative of lower continental crust.
