Tombstone Territorial Park

Tombstone Territorial Park, straddling the Dempster Highway 70 kilometres north of Dawson City in the Ogilvie Mountains, is the most dramatic wilderness park in Yukon Territory — 2,200 square kilometres of exposed Tombstone granite batholith (a mass of 100-million-year-old intrusive rock shattered and sculpted by 300,000 years of Arctic freezing into jagged spires, knife-edge ridges and cirque-carved peaks), overlain by Arctic and sub-Arctic tundra, permafrost wetlands and some of the finest fall colour scenery in North America.

The park’s centrepiece is Mount Monolith and the Tombstone Range — a horizon of dark granite pyramids rising above the tundra that has made the park one of the most photographed wilderness landscapes in Canada. Tombstone is also exceptional wildlife habitat: Grizzly bears, wolves, wolverines, Dall sheep, caribou from the Porcupine Herd, and Golden eagles are all present. The park is accessible from the Dempster Highway, Canada’s only all-season highway to the Arctic.

Late August and early September is the finest time to visit Tombstone — the Arctic tundra turns its spectacular fall palette (crimson bearberry and crowberry, gold willow and dwarf birch, orange mountain avens) against the dark granite spires in a colour display that rivals any autumn scenery in North America. The weather is generally stable in late August (before the first hard frosts), the Grizzly bears are actively feeding on berries (visible on the hillsides at close range from the highway and trails), the light is golden and long, and the highway is dry. July is the prime summer hiking month (snow-free trails, long days, wildflowers on the tundra — Arctic lupine, yellow arctic poppy, white mountain avens). June can have lingering snow on the high routes. The Dempster Highway is open year-round but winter visits require full Arctic cold-weather preparation (temperatures to -50°C are possible).

The Tr’ondëk Hwëch’in (formerly the Han people of Dawson City) and the Na-Cho Nyäk Dun First Nation of Mayo have traditional territories overlapping the Tombstone area — the Ogilvie Mountains were a seasonal hunting and gathering ground for caribou, sheep, and berries for thousands of years. The Tombstone Mountain area was explored by prospectors during the Klondike Gold Rush (1896-1899) but yielded no major gold deposits. The Dempster Highway (completed to Inuvik in 1979) opened the region to vehicle access for the first time; before the highway, the Tombstone area was accessible only by floatplane or horse. Tombstone Territorial Park was established in 1998 by the Yukon government, developed with extensive participation from the Tr’ondëk Hwëch’in and Na-Cho Nyäk Dun, who maintain strong cultural connections to the land.

The Tombstone Range is a Cretaceous-age (approximately 90-100 million years old) granite batholith — a massive body of intrusive igneous rock that crystallized deep in the crust during the final stages of the terrane accretion that built the northern Cordillera. The Tombstone Pluton (as geologists call it) is distinctive for its dark grey granitic composition (richer in hornblende and biotite than most Yukon granites) and its extreme joint and fracture density — the intense fracturing, combined with 300,000+ years of periglacial freeze-thaw action, has shattered the granite into the jagged spires and knife-edge arêtes that define the range’s skyline. The tundra landscape is underlain by continuous permafrost (perennially frozen ground); the permafrost polygons, ice-wedge ponds and thermokarst features visible from the highway are characteristic of the Arctic and sub-Arctic permafrost zone. Climate change is accelerating permafrost thaw and actively reshaping the tundra landscape.

Tombstone is one of the finest wildlife-watching parks in Yukon — Grizzly bears (extremely common in the park; regularly visible from the Dempster Highway and the Grizzly Lake Trail, particularly in late summer when they are actively feeding on berries; the park has one of the highest accessible Grizzly densities in the Yukon), Dall sheep (on the upper ridges and cliff faces of the Tombstone Range), wolves (grey wolves are present in several packs; sometimes visible on the river flats in early morning), Porcupine Caribou (the western edge of the Porcupine Herd’s range crosses the park — caribou may be encountered, particularly in late summer and fall migration), wolverine (present but rarely seen), Arctic ground squirrel (abundant on the tundra slopes; the alarm calls of the ground squirrels are a reliable indicator of Grizzly bear proximity), Golden eagles (nesting on the granite cliffs in summer), and gyrfalcon (the large Arctic falcon; winter resident). The Grizzly bears and the fall tundra wildlife are the dominant experience.

Tombstone’s ecology spans boreal spruce forest in the lower valley bottoms, transitional shrub (willow, alder, dwarf birch) in the sub-alpine, and open Arctic tundra on the higher slopes and ridges — all underlain by continuous permafrost that shapes the drainage, the vegetation and the landscape. The park is part of the greater Porcupine Caribou ecosystem — the 218,000-animal Porcupine Caribou Herd (which calves in the Arctic National Wildlife Refuge in Alaska) uses the Ogilvie Mountains region as part of its annual migration range. The permafrost is the defining and most climate-sensitive ecological feature: as Arctic temperatures rise (Yukon has warmed approximately 2°C since 1948), the permafrost thaws from the surface down, releasing methane (a potent greenhouse gas), destabilizing slopes, and converting dry tundra into wetland. Tombstone is a sentinel site for monitoring climate-driven permafrost change in the sub-Arctic.

Tombstone Territorial Park sits at the intersection of Tr’ondëk Hwëch’in and Na-Cho Nyäk Dun traditional territory — the Ogilvie Mountains are embedded in the oral history, place names, and seasonal land-use practices of both nations. The park was developed as a partnership between the Yukon government and these First Nations, and their cultural values (the spiritual significance of the mountains, the traditional knowledge of the land) are woven into the park’s management. For Canadians, Tombstone has become the visual symbol of Yukon wilderness — the image of the granite Tombstone spires above the crimson fall tundra is on Yukon tourism materials worldwide. The park is a profound statement about what remains of wild Canada.

Tombstone Territorial Park is accessed from the Dempster Highway, 70 km north of Dawson City. Drive the Klondike Highway (Hwy 2) from Whitehorse to Dawson City (536 km; paved; approximately 6 hours), then north on the Dempster Highway (Hwy 5) to the park boundary at Km 70 and the Tombstone Interpretive Centre at Km 71. The Dempster Highway is a gravel road — carry two full-size spare tires, a tire plug kit, and a satellite communicator. Fuel is available in Dawson City (fill up before entering the Dempster; the next fuel is 370 km north at Eagle Plains). The Tombstone Interpretive Centre (open June through September) has park information, trail conditions, and a small exhibit on the natural history and First Nations culture of the park. Free camping at government campgrounds along the highway.

Tombstone Territorial Park is managed by the Yukon government in partnership with the Tr’ondëk Hwëch’in and Na-Cho Nyäk Dun First Nations. The permafrost and the Grizzly bear population are the two most critical conservation features. All food, scented items, and garbage must be stored in a certified bear canister or bear-safe vehicle storage when camping — the park’s Grizzly bears have not been food-conditioned and maintaining that wildness is the highest wildlife-management priority. Stay on designated trails in the sub-alpine and alpine zones to protect the permafrost-sensitive tundra vegetation (cryptogamic crusts and tundra mosses have no root systems below the active layer and are permanently destroyed by compaction). Pack out all waste absolutely; there are no waste-disposal facilities in the backcountry.

The primary hazard in Tombstone is Grizzly bear encounter — the park has a very high Grizzly density and the bears are regularly visible at close range. Travel in groups; make constant noise (call out, clap) in thick shrub; carry bear spray in an immediately accessible holster (not in your pack) and know how to use it; never approach a Grizzly regardless of apparent docility. River crossings on backcountry routes can be serious in high water (late June and July snowmelt). The Dempster Highway is remote — a tire puncture (the road is sharp gravel; two spares minimum) or vehicle breakdown leaves you hours from help; a satellite communicator is essential. Weather changes rapidly and severely; hypothermia risk is real even in July (afternoon temperatures can drop below 5°C with wind and rain). There is no cell service on the Dempster Highway from Dawson City to Inuvik.

No park entrance fee (Tombstone is a Yukon territorial park; free access). Camping at designated government campgrounds (first-come, first-served; no reservations). Campfires permitted at campgrounds with fire rings only (open fires in the backcountry require a permit from the Yukon government — apply in advance; fire ban conditions apply frequently in summer). Bear canisters required for all backcountry food storage. All waste packed out. Hunting is not permitted in the park (traditional harvesting by First Nations members under land-claim agreements is permitted). Motorized vehicles and ATVs are not permitted off the Dempster Highway within the park. Check Yukon government park conditions and any fire ban status before departing Dawson City.

Dawson City (70 km south on the Dempster Highway — the historic Gold Rush capital of the Klondike, with the Dawson City Museum, Diamond Tooth Gerties gambling hall, the Jack London cabin, and a vibrant arts and wilderness community; full services including fuel, groceries, and accommodations), the Klondike River valley (the drive north from Dawson on the Dempster follows the North Klondike River through some of the finest Yukon river-valley scenery), Dempster Highway northward to Eagle Plains (the remote roadhouse at Km 370, the only fuel between Dawson and Inuvik), the Arctic Circle crossing at approximately Km 405, and eventually Inuvik and the Mackenzie Delta define the greater Dempster corridor. Tombstone is the dramatic centrepiece of the Dempster experience.

Time your Tombstone visit for the last week of August or the first week of September for the finest fall colour — the tundra palette at peak (crimson bearberry, gold willow, orange mountain avens, deep burgundy crowberry) against the dark grey Tombstone granite spires in the long, low Arctic autumn light is one of the most spectacular wilderness colour displays in the world. Hike the Grizzly Lake Trail starting at first light (5-6 AM in late August) — the Grizzly bears are most active at dawn, feeding on berries on the south-facing slopes, and the light on the Tombstone Range in the early morning is extraordinary. Drive slowly on the Dempster Highway; the roadside Grizzly encounters (bears feeding on berries within 50 metres of the vehicle) are among the most memorable wildlife experiences in North America.
