Elbow-Sheep Traverse, part 1:
Threepoint Mountain - Mount Rose - Bluerock Outlier & Mountain
with bike approach

Stats:
47.5km total: 2 x 11km bike, 25.5km walk
2,182m total gain: 161+37m on bike, 1,984m the traverse itself
14hrs car-to-car / 12hrs bike-to-bike

Threepoint - Rose traverse is fairly known, bunch of reports on it. Was interested in continuing it and see if possible to make a bigger loop and exit via Cougar Mountain.

Approach / Bike stash: after checking multiple reports on Threepoint-Rose traverse and Cougar Mountain, decided to stash it in between, by a bridge. It would've saved crossing the river, twice. Naive me: the bridge got washed away in 2013 and was never replaced :(
Stashed it there anyway. But in retrospective, the best option if 1km before, or about 600m past Big Elbow campground (yellow dot on the map attached). When they built a new trail after the flooding, there is an access to the river now and it'll definitely save walking distance and time.

Mt Rose - Bluerock (although it looks like a small hump, Outlier's prominence is about 100m.):
from Rose, there are obvious south slopes and small ridge toward Bluerock. When descending, start with a "normal" route and almost at once, take a sharp left; keep to skier's left, toward an obvious white ancient moraine.
Once at a pass, there are two options: take a game trail on climber's right and start scrambling to the Outlier, the ridge is obvious after. Or, traverse left, to an obvious gully and seasonal creek, while you'll save some elevation gain and distance that way, but it should a slog there.


Bluerock exit:
if it's the final point, then above-mentioned scree on the north side toward Mt Rose is the obvious choice, it will be faster and shorter in the end.
There is a gully on the SW side that goes to another valley (joining with the blue line), but it's definitely longer.

Tried to bag next high point, GR2423847, as well, but got hit by multiple storms and decided to bail. Descending SW ridge of Bluerock was ok, mix of some good slabs and scree. Though I guess if to take a gully on skier's left to the ridge and then traverse back to a pass, it should be faster.

NOTE: if the whole traverse from bike stash to Threepoint, Rose and Bluerock is just an easy scramble (on the personal preference but didn't see any need in helmet there), then GR2423847 is definitely at least moderate to the return point; and what lays further, has to be tried yet.


Summary / hints for the future:
- stash bike at yellow mark (see the map)
- there is a good equestrian trail in those valley; unfortunately it's unmarked. If missed, it'll be some bushwacking (tested and got it today :) )
- get some light rubber shoes, i.e. Vibram FiveFingers, from water sports, etc., in some sections, the "trail" goes right on water (horses don't really care). Lost so much time today because of taking shoes off, crossing and putting shoes back :)
