I do not have a GPS track of the winter route from the tram up to San Jacinto. However, whenever I head up the tram to snowshoe, there are skiers and snowboarders. Hopefully, someone on the board can post a GPS track.
Winter route: Round valley trail to Sid Davis drainage to Tamarack Valley > upper Tamarack to base of Miller then go left (west) to base of Miller saddle > north up to Miller saddle > north side of ridge to San Jacinto peak. Numerous ski routes down -- I head back down the same route.
Hope this helps.
Perfect timing -- please post a gps track for Tim, thanks.
Miles of smiles,
