About Seven Sisters

This page shows the current backcountry snow report, avalanche forecast, and weather conditions for Seven Sisters. Check the danger rating, field observations, and Doctor's Orders summary above before heading out.

The Seven Sisters region encompasses the Seven Sisters Provincial Park and the surrounding Coast Mountain terrain east of Terrace, covering the dramatic peaks of the Seven Sisters group and the broader Skeena and Gitnadoix River drainages. This area is defined by extreme relief — peaks rising abruptly from river-level valleys — and the heavily forested lower elevation terrain that gives way to steep, complex alpine couloir and bowl systems above treeline. Highway 16 runs through the Skeena Valley at the base of the region, providing direct access to lower approach routes, but the upper terrain requires significant elevation gain on challenging ground. The snow climate in the Seven Sisters region is maritime in the truest sense, with the Skeena River valley acting as a direct conduit for Pacific moisture far inland and producing some of the highest snowfall totals in the northwest BC coastal mountains. The snowpack is dense, high water-content, and prone to rapid and significant loading during the frequent Pacific storm cycles that track through the Skeena corridor. Rain and freezing rain events reaching to mid-elevation are not uncommon through mid-winter, creating rain-crust layers that become persistent weak layer candidates when buried by subsequent snowfall. Wet avalanche cycles dominate the spring hazard profile, often beginning earlier in the season than comparable terrain at inland latitudes.

Terrain within this zone includes: Seven Sisters Provincial Park, Terrace, Skeena Valley, Gitnadoix River, Kitwanga.
