Trigon Mountain is a remote peak in the Cariboo Range.   It is rarely climbed and it is a big challenge to get to a place where we can spot it.   It lies on the edge of the Premiers Range, glaciated peaks north of Wells Gray Park

The taller peaks of the Premier Range include Mount Sir Wilfred Laurier (3516 m or 11 535 feet), Mount Sir John Thompson (3349m), Mount Sir John Abbott (3398m) and 7 more 10000 foot peaks.

Trigon Mountain is a lesser peak in this area, but it does have one special distinction.   From the top of the mountain (2950m) the glaciers are the source of three river systems.

On the south side of Trigon Mountain is the Thompson Glacier, the source of the North Thompson River.   There are many downstream tributaries of the North Thompson, but it starts at the toe of the Thompson Glacier.   It flows southeast then south for about 307 km km to Kamloops where it meets the South Thompson River to become the Thompson River.

On the western slopes of Trigon Mountain is Raush Glacier, the source of the Raush River.   The Raush flows northwest for 70 km where it meets the 2657 km long Fraser River near Dunster.   The river drains 100 000 hectares in the Cariboo Mountains.   There are two BC Parks protected areas in the Raush River Valley, but there are no roads into the upper area.

On the north side of Trigon Mountain is the South Canoe Glacier, the source of the Canoe River.   The Canoe flows 37km east and northeast to the Valemount area where it empties into the Canoe Reach of Kinabasket Lake part of the Columbia River system which is 2000 km long and has 14 hydroelectric dams along the way.   The Columbia reaches the Pacific Ocean near Portland.

Trigon Mountain was climbed/explored by the noted geologist Rollin Chamberlin who combined exploration, mountaineering and glaciology in the Cariboo Mountains.   He completed 9 major summits in this area.   His daughter Frances Chamberlin Carter became the first woman to climb the highest peak in all 50 US states.   When she climbed into the Trigon area she noted that it was the 3-way divide for three major rivers – Canoe, Raush, and North Thompson.

We will never get to the top of Trigon Mountain, but we plan to follow the Upper North Thompson Forest Service Road as far as we can drive (10 km from the peak).   There are two BC Parks Protected Areas in the valley – North Thompson Oxbows Manteau and North Thompson Oxbows East – areas to paddle and explore.
