Mt Clarence is in the centre of Albany on the south coast of Western Australia. From the top are views of a magnificent harbour and mountains inland. It is also the site of an important war memorial and museum.

This is one site out of many along the south coast of Western Australia for epidosite and unakite. The second is locally known as 'albany granite'. Uninteresting in the rough, they make decent specimens when slabbed and polished. Drilling has confirmed the material is also found at least 100 kilometres out into the ocean. It was formed when Australia pulled away from Antarctica.

Adjacent to Boronia Street in central Albany is the remains of an overgrown historic quarry, not used for over one hundred years. It is on the far north-west portion of Mount Clarence, now surrounded by houses, a park with small waterfall using local stone, and rock tors which can be explored further up the hill. A popular tourist attraction called Dog Rock is nearby.

The quarry shows grey syenogranite traversed by fine grained biotite monzogranite, containing sericite, saussurite, clay-epidote-chlorite in biotite, dark hornblende, with sparse zircon and apatite. Several further quarries are on neighbouring Mount Melville.
