“Part of the Powderface Short Loop and Powderface Loop, providing access to Powderface Ridge.”
— David Mills
From the trailhead, the Powderface Creek Trail goes straight up. It starts off very wide, and a bit gravelly. Things level out briefly, then tip up again before a short and fast descent that levels off as it approaches the first creek crossing. After that, it's a mostly gradual climb [with one sharp pitch] on wide trail all the way to the junction with Prairie Link.
Once you arrive at the Prairie Link Trail
turnoff, keep going straight on the Powderface Creek Trail. It gets steep and loose, and stays that way. For the vast majority of people, it will be hike-a-bike time, as the eroded slope exceeds 20%. Reaching the high point of the trail gives you access to Powderface Ridge, a challenging but fun ride that can be done as an out-and-back to increase the amount of climbing on the ride.
The descent down to the road is rough and loose, and has become quite eroded in spots over the years. No flow here, but fans of olde-school tech XC will be happy. There will be a junction with a hiking trail, but stay left on the main route and continue down to the road.
