[活动召集]本周六Mt.Sproatt雪鞋行(day hiking)

Mount Sproatt:

A gentle summit SSE of Rainbow Lake. Often a deep powder ski destination in January to March via a number of approaches from the 21 Mile Creek valley. Sproatt has a couple of hanging valleys on its northerly slopes which hold vast amounts of the white stuff in prime condition, but it also has east facing and west facing slopes and ridges which allow for lots of exploring and touring. Sproatt has significant meadow complexes that provide for excellent hiking in the summer.


Route 1:

From Hanging Valley Steep little steps. From Rainbow Lake trail up Twentyone mile Creek, continue past normal ascent route, until north of the peak (123:01), then leave the trail and ascend SW into the prominent hanging valley. After a short, steep ski climb up the headwall, the route levels out, allowing easy access to saddle immediately W of Mount Sproatt.

Route 2:

NE side steep forest. This route is a common variation on the hanging valley route. Leave the trail almost immediately that you get into the old growth, and directly head up the northeastern slopes of the peak, initially following a small creek gully. Once on the ridgetop in the alpine, the terrain becomes much less steep.

Trip Report: This is a trip that has been repeated many times, and is ideal in early winter because there is little avalanche danger. Its very steep skiing through the trees.

Park at the small parking lot at the cemetery. From the cemetery, follow the road, going north. There is a gate right at the beginning of the road. The road goes north toward TwentyOne Mile Creek, then turns west at the filtration station. The road ends in about 1 km. From here the trail to Rainbow lake continues. Go a short distance on the trail, then cut up through an old clearcut toward the steep slopes of Sproat.

From the map, you can see approximately the route - it varies slightly every time, but eventually you end up just east of the north ridge of Sproatt at about 4500'. Then follow the ridge up and into the open, and from there ski to the summit. This is often whited out in January. If not whited out, its pretty safe to the summit, but there are various steep slopes which will slide.

Depending on time and whiteout conditions, people usually return the same route. However, if the visibilty is good, we have descended to the hanging valley to the northwest of the peak and then down to the trail. This involves one steep section just before you get back to the Rainbow Lake trail.

Trip Report: This route is a particularly fine winter route, allowing the opportunity to make a number of side trips into very interesting and accessible alpine meadows. Please note that this route is mostly through watershed.

Use the 21 Mile Creek trailhead on Alta Lake Road to begin this trip. Follow the Rainbow Lake Trail into the old growth forest and over the first large creek crossing. At almost three kilometres into the trail, by the second outhouse, begin a gentle rising contour to the left. Within minutes, one should spy a large yellow icicle hanging on a bluff ("the peesicle"). The route climbs a short steep slope to the left (east) of this feature; if you come to a small canyon and roaring creek, you have gone slightly too far--turn to the east slightly and climb up to the peesicle.

Use caution on the short, steep pitch, as it is steep enough to slide in unsettled conditions (One will likely be impressed by the diameter of the remaining trees left in the centre of the slope). After gaining about 80m elevation, one should be able to slide out to the west onto more moderate ground; again, it will be obvious if you have strayed too far to the west at this point.

Moderate climbing to the south quickly gains access to open meadows and glades. One can choose any number of good climbing routes to the left, depending upon snow conditions. As in Rome, all routes lead towards the summit of Sproatt. In good conditions, 45 minutes of climbing will put one on the summit and from there, there are a number of attractive options. Be aware that some of the inviting runs to the north do steepen into cliff bands.
