After a tiring Wedgemount hike on Tuesday, off we went on Wednesday, on a 4x4 excursion up the Callaghan FSR, past the abandoned Northair mine, thence into low-range for a serious crawl up the tote road to the Sproatt Alpine area. This is the track used by Canadian Wilderness Adventures for their jeep tours and winter snow machine adventures. While the FSR to the Northair is modestly a 4x4 path, the turnoff up the branch road near the Northair site soon becomes a most demanding 4x4 route indeed.
The first few kms of bumpy, loose surface was handled readily by our Jeep in high range, but don't try this in much lesser rigs. You'll soon run into steeply ascending, narrow and truly rough stuff that will have you wishing for a pull out, which you won't find. The latter portion of this access road is heavy duty 4x4 driveable only. Be warned.
Although we could've gone further, for this trip we ended up parking at a good spot prior to the last, and worst 1.5 km of tote road (red track on map). The hike from there to the TH is a pleasant, if good climb, through mature Mtn hemlock-Balsam forest.
Once you do reach the TH you'll be knocked out by the superb trail (green track on map) upgrading efforts of the RMOW et al crew, of which MSULKERS is a part. This is great work with a well built path right into the sub-alpine yielding splendid views of Rainbow Mtn, Sproatt Mtn, Gin Peak etc.
Excellent scrambly stuff abounds, along with vistas of Sproatt lake, Tonic Lake etc. We tracked our progress to the end of the new trail, then just wandered around. A great day, and so much nicer than that grunt up from Function Junction.
Here's some maps of the route
About the only good parking spot way up the road on the way to CWA cabin. This is about 1.5 km from the TH
Well built new path, somewhat parallel to the old trail
