Little Known Fall Secrets – Larches of the Kootenays

Little Known Fall Secrets – Larches of the Kootenays

View All Blog Posts

Most people are familiar with the annual show put on by the maples of Eastern Canada, but the Kootenays have their own, equally stunning autumn colour riot, as the larch trees paint the mountains brilliant gold in late September/early October into mid-November.

Often mistaken for their Eastern relative, Tamarack, the Kootenays boast some of the highest concentrations of both Western and Alpine Larch. All three are members of the Larix genus. A confused family of trees, Larix are both coniferous trees (trees with needles and cones) and deciduous (they recycle pigments and drop their foliage each fall), recycling their valuable green chlorophyll molecules by storing them inside the tree itself when the days shorten and the temperature drops, leaving only the yellow and golden-hued carotenoid and xanthophyll pigments in the needles to brighten up the world.

Western Larch 
The Larix Occidentalis is a tall, straight tree found at lower elevations, prized for both lumber and firewood. With up to 30-cm of bark, it can survive repeated forest fires, and can grow to monstrous proportions. The world record Western Larch boasts a 6.7-metre diameter, and they can reach 80 meters in height.

Few of these giants survived the early forestry boom of the Kootenays, but the next generation of larch carpets our low-elevation slopes, and these younger trees still put on an incredible autumn show. Dewar Creek near Kimberley and the Yahk Valley boast extra high densities of Western Larch (you may see these trees on your trek to Monica Meadows and hiking in Kokanee Glacier Park).

Alpine Larch  
The Larix Lyallii are the wind-gnarled and frost-sculpted cousins of the Western Larch and can be found on rocky slopes and alpine meadows at high elevation. Destinations like Brewer Creek, Kokanee Glacier Park, Jumbo Pass, Rockwall Trail (in Kootenay National Park), St. Mary’s Alpine Park, Monica Meadows and Welsh Lake, offer great Alpine Larch viewing, and the annual show begins to light up in mid-late September.

These bonsai-like golden forms against a backdrop of an early snowfall and crystal blue Kootenay skies is well worth a hike. Some ancient Grandmother alpine larches have been leaning into the mountain winds for close to 2,000 years.
