Location

The Pryor Glacier originates in the west between the

and the

and flows north-northeast to enter

to the north of Yermak Point. It passes Wagner Spur and Mount Send to the north. Past Mount Shields it is joined from the southwest by Robilliard Glacier. Svendsen Glacier and Robilliard Glacier feed the Kooperatsiya Ice Piedmont, which joins Pryor Glacier from the south just before its mouth. Features along the Svendsen Glacier and Robilliard Glacier include Mount Simmonds, Mount Theaker, Mount Harrison,

Features

Wagner Spur

. A pointed rock and ice spur along the north flank of Pryor Glacier, southeast of Mount Gorton, at the southeast extremity of Wilson Hills. Mapped by

(USGS) from surveys and United States Navy aerial photography, 1960-62. Named by United States

(US-ACAN) for John E. Wagner, worker in the field of glaciology at McMurdo Station, 1967-68.

Robilliard Glacier

. A valley glacier, long, which flows northeastward through the Usarp Mountains. It rises southward of Mount Simmonds and emerges from the mountains at Mount Shields, where it joins Kooperatsiya Ice Piedmont. Mapped by USGS from surveys and United States Navy air photos, 1960-62. Named by US-ACAN for Gordon Robilliard,

Svendsen Glacier

. A meandering glacier, long, in the Usarp Mountains. It flows northeastward from Mount Marzolf and emerges between McCain Bluff and Lenfant Bluff onto an ice piedmont just west of the terminus of Rennick Glacier. Mapped by USGS from surveys and United States Navy air photos, 1960-62. Named by US-ACAN for Kendall L. Svendsen, USARP geomagnetist at McMurdo Station, 1967-68.

Kooperatsiya Ice Piedmont

. An ice piedmont at the southwest side of Yermak Point on the west shore of Rennick Bay. This area was photographed in 1958 by the Soviet Antarctic Expedition which gave the name "Zaliv Kooperatsiya" to the western portion of Rennick Bay. The US-ACAN has retained the prior name Rennick Bay. For the sake of historical continuity, the name Kooperatsiya Ice Piedmont has been approved for the feature described. Named after the Kooperatsiya, the expedition ship used by the Soviet Antarctic Expedition in 1958.
