The Clear Range is a small mountain range located in the angle of the Fraser and Thompson Rivers in south-central British Columbia. It has a small subdivision just northeast of that confluence named the Scarped Range. The Clear Range totals 16,270 km² (6,280 mi²) and is 75 km (47 mi) north to south and 35 km (22 mi) east to west (at its widest point). The Clear Range and its northward neighbour the Marble Range are both subranges of the Pavilion Range. It and the neighbouring Marble Range line the east bank of the Fraser River north of the town of Lytton, British Columbia. The Clear Range extends as far as the town of Pavilion and is bounded by the south wall of Marble Canyon on the north. The southeast flank of the Clear Range is the Thompson River between Ashcroft and Lytton, while to its northeast are the Cornwall and Trachyte Hills, and beyond them the Arrowstone Hills of the Bonaparte Plateau. The range is horseshoe-shaped, facing the high rangeland-plateau basin of Hat Creek, which drains northeast to join the Bonaparte River, a tributary of the Thompson. All of these areas, including the Clear Range, are classified by geographers as belonging to the Fraser Plateau, which is part of the Interior Plateau. Terrain The outer flanks of the range are steep, particularly on the side of the Fraser, where the northerly peaks are a high plateau-edge almost 2000 m (7000 ft) above the river below. The core of the range is rugged and has a complex series of interlocking valleys. Karst formations throughout the area suggest caves, though none has been discovered, and there are scores of intermittent waterfalls and sub-alpine swamps. The northern edge of the Clear Range is the south wall of Marble Canyon. The highest summits are Blustry Mountain, 2334 m (7657 ft); its neighbor Cairn Peak 2328 m (7638 ft); and north of them, Moore Peak, 2223 m (7293 ft); and Chipuin Mountain, 2170 m (7119 ft). The highest peak in the southern part of the range is Botanie Mountain (bu-TAN-ee), just north of Lytton 2077 m (6814 ft), but higher in the centre of the range is Mount Murray 2153 m (7064 ft). A separate ridge across the Fraser River from Lillooet is named Fountain Ridge. It is geologically distinct, actually a sliver of plate between the Fraser and Yalakom Faults. Arthur Seat, 1672
