Richard, did you use our trail?
Up to the where the route crosses over from the south side to the north (near the E-ledges), I was following a sled track. (Turns out there were two that were dropped just above where you drop down to cross the stream for the ledges). From there on (to LBSL and beyond), there was an excellent snowshoe track. I turned left for Thor, just beyond a few tent platforms near the lake.
Being a lightweight has its advantages... I carried snowshoes, but never felt the need to put them on. I punched thru a few times on the way up Thor, but never went in much deeper than my knees.
