Hawks Crag

Hawks Crag is a prominent landmark in the lower Buller Gorge, where the road has been excavated through a bluff that drops into the Buller River.

Hawks Crag and the surrounding area is made of rock named Hawks Crag Breccia – massive, thick beds of sedimentary rocks containing angular fragments that have been tilted about 40° to the right (west). Low-grade uranium mineralisation was discovered in the Hawks Crag Breccia in 1955. But despite prospecting over the next two decades, no economically recoverable deposits of uranium were found.
