Approximately in area, the icefield's shape is roughly triangular, with an apex on its northern side, where a short gap separates the ice-mass from that of the smaller
Overseer Icefield. Some reckonings include the icemasses of the Overseer massif, in which case the Pemberton Icefield's area may be considered to be ~ larger in area.
Overseer Mountain is the highest summit in the region lying in the triangle between the basins of the Lillooet, Squamish-Elaho and Cheakamus-Green valleys, although the highest named summit in the Pemberton Icefield proper is Longspur Peak, on the main icefield's northwest flank above the
Ryan River, although a higher, unnamed summit lies in between them, at the northernmost edge of the icefield. Just east of Longspur are Kwtamts Peak and
Sisqa Peak (names from St'at'imcets language of
Lil'wat people, whose traditional territory includes the eastern reaches and related valleys of the icefield). The southernmost summit of the icefield is
Exodus Peak, which lies in the angle between the uppermost reaches of the Squamish River and the valley of the
Elaho River, a tributary of the Squamish.
Streams Streams having their origin in the icecap include the
Squamish River and
Soo River on its southern edge,
Rutherford Creek of its eastern point, the
Ryan River off its northeast side, and tributary streams to the
Elaho River, a tributary of the Squamish, on the west, and the south fork of
Meager Creek, on its north side, another tributary of the Lillooet. Other smaller icefields nearby are the
Ipsoot Glacier (also known as the Ipsoot Icefield) to the east, on the north side of Rutherford Creek, and the
Powder Mountain Icefield to the south, beyond the divide separating the headwaters of the Squamish and Soo Rivers. ==Popular use==
