The glacier is named after the Italian geologist and palaeontologist Antonio Stoppani (1824–1891). It lies in Alberto de Agostini National Park, in Chile's Magallanes and Chilean Antarctica Region, on Isla Grande de Tierra del Fuego.

The glacier forms part of the Alberto de Agostini National Park, which protects the natural heritage of Tierra del Fuego and its native ecosystems.

The glacier lies in Alberto de Agostini National Park on Isla Grande de Tierra del Fuego, in Chile's Magallanes region. It ends about 12 km from Yendegaia Bay, where it gives rise to the Yendegaia River. Approach is by boat or on foot from the bay area; the sources give no marked trail or facilities.

The glacier functions as the source of the Yendegaia River, contributing to the regional water system through its continuous ice melt process.
