To approach the chute, park at the White Pine trailhead and follow the trail towards the first branch and take the right fork by the creek and wrap around into Red Pine Canyon. From here keep working up the canyon until you reach the bridge that crosses over to Maybird. Then hike to the E, away from the bridge and you'll end up on the apron to the chute. From here just boot up until you hit the ridge, or get as high as is required.
