Part 31 Antarctic specially protected area No. 131

  Canada Glacier, Lake Fryxell, Taylor Valley, Victoria Land.

  Latitude 77 37 S, longitude 163 03 E.

  The designated Area encompasses most of the glacier forefield area on the east side of the lower Canada Glacier, on the north shore of Lake Fryxell (77° 37 S, 163° 03 E). The south boundary of the Area is defined as the shoreline of Lake Fryxell, to the water’s edge, extending about 1 km east from where the Canada Glacier toe meets Lake Fryxell. The west boundary of the Area follows the edge of the Canada Glacier. The south-east corner is near the neck of a small peninsula extending into Lake Fryxell. The peninsula, outside of the Area, is marked by a large rock (split) surrounded by a circle of rocks which was a benchmark for the 1985 NZ survey of the original SSSI. A wooden post marking Dry Valley Drilling Project Site 7 (1973) is about 10 m to the north-west of this point. A moraine ridge extends from the south-east corner upward and in a northerly direction: this ridge defines the eastern boundary of the Area. The ridge dips sharply before joining the featureless slope of the main Taylor Valley wall: the north-east corner of the Area is in this dip and will be marked by a cairn. A cairn will also be placed on a knoll on the ridge 450 m from the south-east corner point. Above the central flush a slope of lateral moraine of fairly even gradient extends upward and parallel to the glacier for about 1 km. At the top of this slope is a small knoll (220 m) about 300 m from where the glacier emerges into the Taylor Valley: a cairn and signpost will mark the boundary of the Area at this point. The upper, northern boundary of the Area extends from the Canada Glacier to the boundary markers on the knoll and thence declines in elevation in an easterly direction for 1.7 km to the north-east boundary cairn.
