I believe there is some more information on this site if you search including a GPS track..hopefully the snowshoe track will be back in service sometime in the near future, after this big snow event going on...we had a snowshoe trench, though windblown snow in spots, to follow on 1-22-15, that made it very easy!! we just did the Engine Hill to Isolation Trail BW and took Isolation and Davis Path to the summit spur trail...other hiking sites too may have info for you...hope it works out for you..!
