It is the largest river in Antarctica, and at 30 kilometres in length, it is also the longest.
The highest peak is Vinson Massif and the longest river is the seasonal, melt-water river Onyx.
This seasonal, melt-water river flows about 32 K from the base of the glacier to the sea.
The Onyx River is an 18-mile long melt water stream that flows into Lake Vanda from a glacier at the end of the valley.
The Onyx River is both the largest and longest river in Antarctica. It is 30 kilometers in length.MoreIt is a seasonal runoff river. From its Wikipedia entry:"The Onyx River is an Antarctic melt-water stream which flows westward through the Wright Valley from Wright Lower Glacier and Lake Brownworth at the foot of the glacier to Lake Vanda, during the few months of the Antarctic summer."

All 'rivers' on Antarctica including the Onyx are not true rivers. They are seasonal, melt-water flows, none of which flow into the sea.
