Description

Spire Peaks is set within Garibaldi Provincial Park and is part of the Garibaldi Ranges of the Coast Mountains. [3] It is situated 55 km (34 mi) north of Vancouver and 6 km (4 mi) north-northwest of line parent Mamquam Mountain, with the Mamquam Icefield between the two. The southwest summit has an elevation of 2,279 meters and the northeast peak is 2,245 meters, and they are separated 500 meters apart. [6] Topographic relief is significant as the north aspect rises 1,280 meters (4,200 feet) in two kilometers (1.2 mile). Precipitation runoff and glacial meltwater from the north side of the peak drains to Pitt River, and the southern slope drains to Skookum Creek, thence Mamquam River.

History

The first ascent of the summit was made July 22, 1913, by Don Munday and Ben Hanafin. [7] Don would write a poem about the climb, Spire Peak—First Ascent, and recall that the rocks "were as hot as a stove." The toponym was officially adopted March 9, 1979, by the Geographical Names Board of Canada. [4]

Climate

Based on the Köppen climate classification, Spire Peaks is located in the marine west coast climate zone of western North America. [8] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Spire Glacier on the northeast slope.

<span class="mw-page-title-main">Joffre Peak</span>

Joffre Peak is a 2,721-metre (8,927-foot) mountain summit located in the Coast Mountains, in Joffre Lakes Provincial Park, in southwestern British Columbia, Canada. It is the second-highest point of the Joffre Group, which is a subset of the Lillooet Ranges. It is situated 26 km (16 mi) east of Pemberton and 11 km (7 mi) northeast of Lillooet Lake. Joffre is more notable for its steep rise above local terrain than for its absolute elevation as topographic relief is significant with the summit rising 1,500 meters (4,920 ft) above Cayoosh Creek in 4 km (2.5 mi). The nearest higher peak is Mount Matier, 1.6 km (1 mi) to the south. The mountain's climate supports the Matier Glacier on the southwest slope, and the Anniversary Glacier on the southeast slope. Precipitation runoff from the peak drains into Joffre Creek and Cayoosh Creek which are both within the Fraser River watershed.

<span class="mw-page-title-main">Mount Weart</span>

Mount Weart is a 2,835-metre (9,301-foot) triple-summit mountain located in the Garibaldi Ranges of the Coast Mountains, in northwestern Garibaldi Provincial Park of southwestern British Columbia, Canada. It is situated 14 km (9 mi) northeast of Whistler, and its nearest higher peak is Wedge Mountain, 3.7 km (2 mi) to the south, which is the only peak within the park higher than Weart. The Armchair Glacier rests below the west aspect of the summit, and the massive Weart Glacier spans the northern and eastern aspects of the mountain. Precipitation runoff from the peak and meltwater from the glaciers drains into Wedgemount Lake and tributaries of the Lillooet River.

<span class="mw-page-title-main">Overlord Mountain</span>

Overlord Mountain is a 2,625-metre (8,612-foot) glacier-clad peak located in the Garibaldi Ranges of the Coast Mountains, in Garibaldi Provincial Park of southwestern British Columbia, Canada. It is the highest point of the Fitzsimmons Range, which is a subset of the Garibaldi Ranges, and can be readily seen from the Whistler Blackcomb ski area. It is situated 15 km (9 mi) southeast of Whistler, and its nearest higher peak is Mount Macbeth, 3 km (2 mi) to the north-northeast. The Benvolio Glacier rests below the south aspect of the summit, the Fitzsimmons Glacier on the east aspect, and the expansive Overlord Glacier spans the northern and western aspects of the mountain. Precipitation runoff from the peak and meltwater from its glaciers drains into tributaries of the Cheakamus River. The first ascent of the mountain was made in 1923 by Phyllis Munday and Don Munday via the Benvolio Glacier. The mountain's descriptive name was recommended by the Garibaldi Park Board and officially adopted on September 2, 1930, by the Geographical Names Board of Canada.

<span class="mw-page-title-main">Mount Benvolio</span>

Mount Benvolio is a 2,613-metre (8,573-foot) glacier-clad peak located in the Garibaldi Ranges of the Coast Mountains, in Garibaldi Provincial Park of southwestern British Columbia, Canada. It is the second-highest point of the Fitzsimmons Range, which is a subset of the Garibaldi Ranges. It is situated 15 km (9 mi) southeast of Whistler, and its nearest higher peak is Overlord Mountain, 0.7 km (0 mi) to the northwest. The Benvolio Glacier is set on the western slope of the peak, the Diavolo Glacier spreads out below the eastern aspect of the summit, and the Fitzsimmons Glacier descends the north slope. Precipitation runoff from the peak and meltwater from its glaciers drains into tributaries of the Cheakamus River.

<span class="mw-page-title-main">Handcar Peak</span>

Handcar Peak is a 2,338-metre (7,671-foot) mountain summit located in the Railroad Group of the Coast Mountains, in the Pemberton Valley of southwestern British Columbia, Canada. It is situated 38 km (24 mi) northwest of Pemberton and 3 km (2 mi) west of Locomotive Mountain. Precipitation runoff from the peak drains into Sampson Creek and Buck Creek which are both tributaries of the Lillooet River. Handcar Peak is more notable for its steep rise above local terrain than for its absolute elevation as topographic relief is significant with the summit rising over 2,050 meters (6,725 ft) above Lillooet River and Pemberton Valley in approximately 4 km (2.5 mi). The mountain's name was proposed in 1978 by mountaineer Karl Ricker of the Alpine Club of Canada, in association with Railroad Pass, Railroad Creek and other railroad-related names of the immediate vicinity. The toponym was officially adopted January 23, 1979, by the Geographical Names Board of Canada.
