Hudson’s Hope, British Columbia is well-known for its massive hydroelectric dam and Williston lake, however, this area also has some fantastic geographic features such as the Portage Mountain Steam Vents. These naturally occurring vents are just outside of town and are accessible by mountain bike, foot or ATV. They also provide great views of the WAC Bennett dam and Williston and Dinosaur lakes. Add this adventure to your summer or winter bucket list: you won’t regret it!
Park at the trapper’s shack on Canyon drive, just west of Hudson’s Hope. Ride to the junction of the power lines and Canyon drive, then follow the lines until they head north. This upslope section is heavily eroded, so you make have to hike-a-bike for 500 meters or more. You will eventually emerge on the bottom slope of a small ski hill. Ride upslope to the lodge, then head east down the road.
Two hundred meters past the ski lodge is a junction, take the narrow road heading east and follow it downslope to the power lines right-of-way. Head north, until the trail switchbacks around and over a small creek, then upslope to a level area. The trail head to the steam vents is just on the east side of the road.
This ATV width trail winds its way downslope along a pine and spruce covered ridge and emerges on the rim of the Dinosaur lake canyon. A short trail runs downslope through an aspen stand then emerges on a grassy slope.
Interestingly, these vents don’t smell like rotten eggs (sulphur) and my guess is that they are more prominent in winter when there is a major temperature differential. There is room for a small camp on the south side of the vents, but you are fully exposed to the elements and there is no water in the area.
These steam vents are the only terrestrial geothermal feature–that I am aware of–in northeastern British Columbia. They are well worth a visit. Furthermore, there are some interesting sand dunes on the northwest side of Portage Mountain. Check out my post about the dunes and the massive earth work Art Project that is located there: Hidden in the Sands.
