A hardpan consisting of a strongly cemented layer of fine grained sediment about a metre thick, occurs over highly-weathered Pliocene gravels (King 1982) on a hill top south of Yackandandah, on the western side of the Kiewa Valley (Photo 14). At this Site, referred to as Garvey’s Hill, the gravels have been sluiced for gold. The indurated sediments are finer grained than the typical Tallangatta hardpan material but appear to be analogous. The isolation of the Garvey’s Hill site on a hill top to the west of the study area, makes it difficult to relate directly to the Tallangatta Hardpan in the piedmont sediments, or to the cemented Pliocene gravels at Bonegilla and along the Lake Hume shore line in the Mitta Mitta arm.
