The boundaries of Wells Gray Park encompass 60 percent of the drainage basin of the
Clearwater River, and most water that originates in the park flows into this river. The northern two-thirds of the park is extremely rugged with relief ranging from
Clearwater Lake at an elevation of to at Mount Lyons on the northern park boundary, west of Mount Pierrway. These summits are part of the Cariboo Mountains, and most of the east boundary of the park follows the mountain divide between drainage into the
North Thompson River and into the Clearwater River. Individual mountain groups dominate the topography of the northern park region and are separated by deep
glacial valleys, several of which contain large lakes such as Clearwater,
Azure and
Hobson. The ruggedness of its features has ensured that northern Wells Gray remains little known except to the hardiest of backpackers. The southern third of Wells Gray Park is traversed by the Clearwater Valley Road, although large areas are accessible only by trail. The dominant topography features volcanic plateaus, lava flows and deep canyons which are crowned by several peaks over high. The waterfalls, for which Wells Gray is famous, usually result from the interaction of volcanic eruptions and glacial activity. The best known is
Helmcken Falls, the fourth highest waterfall in Canada, which plunges over the edge of one of these volcanic plateaus.
Highest mountains The eight highest mountains in Wells Gray Park are:
1) Mount Lyons, 2946 m. The first recorded ascent was made by Bill McKenzie and Roger Wallis on August 18, 2005. It is named after
Chess Lyons, Wells Gray Park surveyor in 1940, naturalist, author, photographer, and explorer.
2) Mount Goodall, 2930 m. The mountain consists of 11 distinct summits and extends for nearly 8 km in a northwest to southeast direction. On the northeast side, an unbreached wall of rock and ice rises between 400 m and 1,300 m from the Goodall Glacier. The first ascent was achieved on August 21, 2006, by Roger Wallis, Don Chiasson, and Jim Lundy. They established its height, only 16 m lower than Mount Lyons. As of 2022, only four of Goodall's 11 summits have been conquered. Mount Goodall is one of six peaks in this area named in 1966 in honor of Canadian soldiers from the Quesnel area who were killed in action during World War II; it is named after Trooper Walter Henry Goodall, age 24.
3) Garnet Peak, 2876 m. This is a prominent landmark from many viewpoints in southern Wells Gray Park. It is located north of Azure Lake. The first ascent was by Hugh Neave, Tor Schmid and Barbara Hargreaves on August 29, 1974. It was long believed to be the park's highest mountain until expeditions to the north boundary found the above two peaks were higher.
4) Black Cone, 2861 m. This is the second highest summit of the Goodall group and has been unofficially called "The Black Cone". Its first ascent was on July 30, 2012, by Paul Geddes, Norm Greene, and Bill McKenzie.
5) Mount Pierrway, 2854 m. It was first climbed in 1969 by Art Maki and Art Wilder. The second ascent was in 1987 and the third in 2005. This honors another World War II casualty, Private Alfred Pierrway, age 22.
6) "Unnamed Peak, 2847 m, 3.7 km WSW of Mount Pierrway". It is located on the north park boundary near Mount Lyons. As of 2022, there is no record of this peak being climbed, therefore it is Wells Gray Park's highest unclimbed mountain.
7) Mount Hugh Neave, 2829 m. Located east of Hobson Lake and north of Garnet Peak. Hugh Neave, first to summit Garnet Peak, and Peter Cowan attempted to climb it in 1972 via Hobson Glacier to the east, but were forced to turn back by difficult terrain. It was named after Hugh Neave after his death in 1988. Two expeditions in the 1990s, two in 2015, and one in 2017 failed to reach the summit. The first successful ascent was on August 27, 2019, by JF Labranche and Travis Goodridge.
8) "Unnamed Peak, 2797 m, 3.1 km SE of Mount Beaman". ==History==
