Puntapin Rock is a granite rock formation[1] located approximately 4 km (2.5 mi) south east of Wagin and approximately 30 km (19 mi) west of Dumbleyung in the western Wheatbelt region of Western Australia.
[3] It is found in the Yilgarn Block and composed of granite, a partially recrystallized archean adamellite that is mostly homogeneous.
[4] Puntapin Dam was built on the north side[3] of Puntapin Rock in 1929 with a catchment area of 41 ha (100 acres) to replace Badgarning Dam, found 8 km (5.0 mi) west of Wagin, that had been completed in 1912 but continually leaked.
The granite dome, with its numerous gnamma holes, is a natural water catchment area used by the Noongar as well as the early sandalwood cutters and kangaroo hunters.
[2] The rock is part of a dreaming trail that extends from the south coast near Augusta to the Great Victoria Desert country to the north east.
