I am not sure I understand.
The best approach is from Center Basin since the trail is fairly visible to the top of Junction Pass. The trail from the top of the pass heading south down to Shepherd Pass trail is difficult to find, if not follow. It is pretty much washed out from rock slides. But it is always easier going downhill.
I can go into more detail if you need.
I have always taken the Center Basin route up and over Junction Pass, down to the Shepherd Pass trail, then up and over Shepherd Pass. Depending on where I was heading, I would head down to Tyndall Creek, or up and over Rockwell Pass (cross country) to Wright Lakes.
If you approach Junction Pass via Center Basin, Golden Bear Lake, I camp at the lake above. Contrary to a post many years ago, the trail actually comes withing a few hundred meters of the lake. As seen in my photos, a beautiful lake to camp at and to attack the pss the next day.
If you want to approach from Shepherd Pass trail. I can help, but the trail is much more difficult to find. But there are points along the way.
if you have access to satellite topo take a look.
