Location

edit

The Byrd Glacier flows eastward between theBritannia Rangeto the north and theChurchill Mountainsto the south. It discharges into the Ross Ice Shelf atBarne Inlet.[1] Its mouth lies betweenCape Kerrto the north andCape Selborneto the south.[2][3] The valley below the glacier used to be recognised as one of thelowest points not to be covered by water on Earth(assuming ice does not count as water), reaching 2,780 metres (9,120 feet) below sea level.[4]

The glacier was named by the NZ-APC after Rear AdmiralRichard E. Byrd,United States Navy,American Antarctic explorer.[1]
