Slesse Mountain, usually referred to as Mount Slesse, is a mountain just north of the US-Canada border, in the North Cascades of British Columbia, near the town of Chilliwack.

For example, its west face drops over 1,950 m (6,400 ft) to Slesse Creek in less than 3 km (1. 9 mi). It is also famous for its huge Northeast Buttress; see the climbing notes below. The name means "fang" in the Halkomelem language.

Most of Slesse Mountain is made up of the granitic rocks of the Chillwack Batholith, which intruded the region after the major orogenic episodes for the region, beginnging around 30 million years ago. A batholith (from Greek bathos, depth + lithos, rock is a large emplacement of Igneous intrusive (also called plutonic rock that forms Orogeny (Greek for "mountain generating" is the process of natural Mountain building and may be studied as a tectonic structural event as a geographical event and The primary rock on Slesse is grey diorite from the Batholith. However the summit ridge and the west face are composed of Darrington Phyllite, a metamorphic rock, produced by contact metamorphism with the rock of the Batholith and with an intrusion of granodiorite. Darrington is a town in Snohomish County, Washington, United States. Phyllite is a type of foliated Metamorphic rock primarily composed of Quartz, Sericite Mica, and chlorite; the rock represents Metamorphic rock is the result of the transformation of an existing rock type the protolith, in a process called Metamorphism, which means "change Metamorphism can be defined as the solid state recrystallisation of pre-existing rocks due to changes in heat and/or pressure and/or introduction of fluids i Granodiorite (ˌgrænəˈdaɪəraɪt/ /ˌgreɪn- is an intrusive Igneous rock similar to Granite, but contains more Plagioclase than Potassium feldspar [1]

The site itself was supposed to have been consecrated by the Cemeteries Act after the discovery of the crash site and associated human remains, some of which were gathered into a common grave, others found by climbers and hikers have been placed in a "shrine" out of the weather in a discreet location. In the 1990s the provincial government, under pressure from the Families of Slesse organization, finally passed legislation to enshrine protection of the site, which was under threat from clearcut logging at the time, and markers have been placed on trails leading into the site requesting it be respected by hikers and others accessing it.

Slesse Mountain was first climbed on August 10, 1927, by Stan Henderson, Mills Winram, and Fred Parkes, via a route starting from Slesse Creek. The standard route today is the Southwest Route, which involves approximately 1,650 m (5,413 ft) of ascent, a good deal of scrambling and some sections of technical rock climbing up to class 5.6.
