The whole north - north-east side of Deeks and Windsor is either big second generation trees, clear cut, or horrible devils club and salmon berry. Looking up from Phyllis Lake, I would not recommend coming down from Windsor area. Surrounding the lakes is horrible almost impossible bushwhacking and any farther puts you in the watershed. I personally think coming down from Deeks peak to Lost Lake hut and then up the ridge from the hut and over is the best idea. Was up at the hut last weekend and a trail up looks doable. See photo below of the route I'm thinking. Looking from the Phyllis Creek FSR this seems very feasible also. I attached some photos from this fall of the area to get an idea - Russell
This looks like quite a promising route.
Also, from the perspective of future use, having pre-existing huts along the route would certainly be no bad thing for those less interested in doing 80+km days.
A Sunshine-Coast-Trail style 'civilized' way of doing things would be:
HSCT to Lost Lake Hut
Lost Lake Hut to Mountain Lake Hut
Mountain Lake Hut to Squamish.
Extending further heads up either Brohm Ridge or to Elfin Lakes (if one *really* wanted to try the glacier crossing in summer) ... and then there is the need for a similar stopping point somewhere between there and Whistler. Not a large hole to have to fill, in the grand scheme of things. Having such huts would also make it more likely that the trail didn't quickly become another 'fools gold' route.
So, Vancouver - Whistler could be anything from an *ambitious* 2 day to a week long trip ... only needing one more shelter to make it viable for hiking.
For fastpack/trail-run style, one day to Mountain Lake Hut, one to Brohm Ridge Lodge, then one to Whistler is also appealing.
