Mount Usborne (Spanish: Cerro Alberdi) is a mountain on East Falkland.

At 705 m (2,313 ft) above sea level, it is the highest point in the Falkland Islands.

It is only 5 metres (16 ft) taller than Mount Adam, the highest peak on West Falkland.

It is named after Alexander Burns Usborne,[2] master's assistant on HMS Beagle, the ship that took Darwin on his famous voyage.

The handful of Falklands mountains over 600 m (2,000 ft) have ... pronounced corries with small glacial lakes at their bases, morainic ridges deposited below the corries suggest that the glaciers and ice domes were confined to areas of maximum elevation with other parts of the islands experiencing a periglacial climate.
