One of only four cirque lakes found on mainland Australia. Situated at ca.1,800m altitude, in a periglacial setting within the Kosciuszko National Park, it is surrounded by alpine herb fields, heaths, fens and bogs that support various native plants and animals, including rare, vulnerable and endangered species such as the Mountain pygmy possum (Burramys parvus), the Alpine tree frog (Litoria verrauxii) and the anemone buttercup (Ranunculus anemoneus), as well as several invertebrate species restricted to the alpine zone. Human activities include conservation education, skiing, and ice climbing. Possible impacts of climate change are seen as potential threats to the site.
