Location and surroundings
Robertson Peak belongs to the chain North American Cordillera > Pacific Coast Ranges > Coast Mountains > Southern Pacific Ranges > North Vancouver Ranges > Chehalis. It is in Canada, in British Columbia, within Area C (Sasquatch Country) and the Fraser Valley Regional District. At 2,252 m, it is the highest mountain in Chehalis, and the range itself is the high point of that subrange.
The mountain sits in a rugged coastal range where steep forested slopes give way to higher alpine ground. In this part of British Columbia, travel is shaped by wet weather, dense vegetation at lower elevations, and rough terrain higher up. The peak is part of a compact cluster of summits rather than an isolated mountain, so approaches and views are influenced by surrounding ridges and neighbouring peaks.
Neighbouring peaks
Robertson Peak is surrounded by several nearby summits, with Mount Thirsk the closest at 1,586 m, 2.5 km to the NE. Other neighbours include higher and lower peaks spread around the range, showing how Robertson Peak sits among a busy alpine skyline.
- Mount Thirsk — 1,586 m, 2.5 km NE
- Mount Lamont — 1,994 m, 7.3 km W
- Grainger Peak — 2,183 m, 14.6 km SE
- Mount Glendinning — 2,053 m, 14.8 km NW
- The Witness — 1,750 m, 15.2 km SW
- Nursery Peak — 2,098 m, 15.4 km SE
- Mount Judge Howay — 2,262 m, 16.3 km S
- Ashes Peak — 2,128 m, 16.4 km NW
The nearest higher peak is Mount Judge Howay, which rises slightly above Robertson Peak. That makes Robertson Peak a major summit in its own right, but not the highest point in the wider area.
The view from the summit
From Robertson Peak, the highest peaks within 25 km form a ring of larger summits in several directions. To the E lies Mount Breakenridge at 2,395 m, the tallest of the nearby giants. Other high points include Ember Mountain to the NW, Old Pierre Mountain to the W, and Mount Clarke to the SE.
Nearby high ground also includes Remote Peak and Pukulkul Peak to the west, both within the same broad mountain system. The summit outlook is therefore one of layered ridges and scattered high peaks rather than a single dominant horizon.
- Mount Breakenridge — 2,395 m, 24.2 km E
- Ember Mountain — 2,256 m, 17.8 km NW
- Old Pierre Mountain — 2,231 m, 22.6 km W
- Mount Clarke — 2,159 m, 16.5 km SE
- Remote Peak — 2,129 m, 21.0 km W
- Pukulkul Peak — 2,114 m, 23.9 km W
The range
Robertson Peak belongs to Chehalis, the highest of 51 named peaks in that range. The range’s high point is therefore Robertson Peak itself, at 2,252 m. In the wider mountain hierarchy, Chehalis sits inside the North Vancouver Ranges, which are part of the Southern Pacific Ranges of the Coast Mountains.
This is a mountain area of compact but substantial relief, where many named peaks rise close together. Robertson Peak’s rank at the top of Chehalis gives it special prominence within the subrange, even though higher summits exist elsewhere in the surrounding Coast Mountains.
Climate and weather
Climate estimates from NASA POWER for 2001–2020 suggest that the summit of Robertson Peak is cold for much of the year. The warmest month is July, at about 6 °C, while January is the coldest month, at about -8 °C. Mean temperatures above freezing at the summit are most likely in May, June, July, August and September.
Precipitation in the surrounding area is about 2,350 mm a year. The wettest month is November, at about 365 mm, and the driest is July, at about 60 mm. In this part of British Columbia, the main weather hazards are prolonged rain, rapid cloud build-up, wet snow at higher elevations, slippery rock, and poor visibility after storms.
Best time to visit
For Robertson Peak, the most workable months are usually the ones when the summit is above freezing more often: May through September. Within that window, July is the warmest month on average, while May and September can still feel cool and unsettled at elevation.
Because the surrounding area is very wet, the drier part of the year is helpful for travel, and July is the driest month in the climate record used here. Even then, mountain weather can change quickly, so snow patches, wet ground and low cloud remain possible well into summer.
Nature and wildlife
The slopes around Robertson Peak are typical of the southern Coast Mountains: dense forest at lower elevations, then subalpine scrub, rock, snow patches and open alpine terrain higher up. The wet coastal climate supports lush vegetation below treeline, while the summit area is more exposed and sparse.
Wildlife in this region can include mountain goats, black bears, deer and smaller alpine species, with birdlife adapted to forest and high-country conditions. Travel here often means moving through wet forest, steep gullies and rocky ridges, so route-finding and weather awareness matter as much as fitness.
Guides and organised ascents
For a mountain like Robertson Peak, a certified guide is sensible if you are not experienced with steep, remote terrain, route-finding and changing coastal weather. In Canada, the main professional body is the Association of Canadian Mountain Guides, which is an IFMGA/UIAGM member. The national alpine club is the Alpine Club of Canada.
Visitors in Canada also commonly look to established mountain schools such as Yamnuska Mountain Adventures in Canmore and Canada West Mountain School in West Vancouver. A guided ascent usually includes route planning, hazard assessment, technical instruction and the right equipment for the season. The cost depends on the number of days, group size, hut nights and gear needs.
Safety and preparation
Robertson Peak demands preparation for steep ground, wet rock, cold conditions at altitude and long stretches away from services. Even in summer, the summit can be cool and exposed, and the surrounding terrain may be slippery after rain. Good footwear, navigation skills, layered clothing and a conservative weather plan are important.
For mountain rescue in Canada, the emergency number is 911. It reaches general emergency dispatch, including search and rescue teams where available. In remote terrain, tell someone your plan before leaving and be ready for rapid weather changes.
Interesting facts
Robertson Peak is the highest of 51 named peaks in Chehalis, and it is also the range high point. Its nearest higher neighbour is Mount Judge Howay, 16.3 km to the S, which places Robertson Peak just below one of the better-known summits in the area.
The mountain is part of the North Vancouver Ranges in the Coast Mountains, within the broader North American Cordillera. That position puts it in a long mountain chain that runs through western North America, while Robertson Peak itself remains a distinctly local high point in Chehalis.
FAQ
How high is Robertson Peak? It rises to 2,252 m.
Where is Robertson Peak? It is in Chehalis, in Area C (Sasquatch Country) of the Fraser Valley Regional District, British Columbia, Canada.
What range is Robertson Peak in? It is part of Chehalis, within the North Vancouver Ranges of the Coast Mountains.
What is the nearest higher peak? Mount Judge Howay, at 2,262 m, lies 16.3 km to the S.
Is there water on the way to Robertson Peak? In this wet mountain region, water may be available from snowmelt or seasonal runoff, but it should be treated before drinking. Carry enough for the day, usually about 1.5 to 3 litres depending on heat and route length.
Is mobile phone coverage reliable? Coverage in the hills is often patchy and depends on the operator. On open ridges it may be better, while in valleys and behind ridges it can fail. 112 reaches emergency services over any available network, and maps should be downloaded before setting out.
When is the best time to visit? The most suitable months are usually May to September, when summit temperatures are more often above freezing.
