  Linnaeus Terrace, Asgaard Range, Victoria Land.

  Latitude 77 35 50 S, longitude 161 05 00E.

  Linnaeus Terrace (77° 35 50 S, 161° 05 00 E) is an elevated bench of weathered Beacon Sandstone approximately 1.5 km in length and 1 km in width. It is located at the east end of the Asgaard Range, 1.5 km north of Oliver Peak (77 36 40 S, 161° 02 30 E) at an elevation of about 1 600 m. The Area overlooks the South Fork of the Wright Valley, is about 4 km from Don Juan Pond and 10 km from the terminus of the Wright Upper Glacier.

  On the ground, the lower (northern) boundary of the Area is characterised by the presence of a predominantly sandstone outcrop of approximately 3 m in height which extends for much of the length of the terrace. The lower boundary of the Area is defined as the upper edge of this outcrop, and as straight lines adjoining the visible edges where the outcrop is covered by surface talus. The upper (southern) boundary of the Area is characterised by a line of sandstone outcrop of about 2–5 m in height, occurring between the elevations of 1 660–1 700 m about 70 m above the general elevation of the terrace. The upper boundary of the Area is defined as the uppermost edge of this outcrop, and shall be considered a straight line between the visible edges where the outcrop is covered by surface talus. The west end of the Area is defined as where the terrace narrows and merges with a dolerite talus slope on the flank of the north-west ridge of Oliver Peak. The boundary at the west dips steeply from where the upper outcrop disappears, following the border of the dolerite talus with the terrace sandstone down to the western-most corner. The east boundary is defined as the 1 615 m contour, which follows closely the edge of an outcrop which extends much of the width of the terrace. At the southern-most corner of the Area the terrace merges with the slopes into the valley to the east: from this point the boundary extends upward to the 1 700 m contour, from where it follows the line of outcrop defining the south boundary.
