As you are skiing down the Mountain run, you will pass Headwall chair on your left about 2/3's of the way down.
There will be a flatter portion with a rock knoll on your left with signage on the run.
Home Run splits off to the right here.
It is a wide cat track that cuts underneath Moseley's and the West Face Alternates.
If you want to get back to the Funitel, KT-22, Exhibition and Red Dog base area, then this is a better option as you won't have to walk or push from the low spot at the base of the Mountain run.
It ends on the lower portion of Julia's Gold, just above KT-22, so be careful when merging at the end.
