A suggestion in the US Trails group chat was to mark walkable areas - this to me feels more accurate but probably nearly impossible to accurately convey as well. From a previous thread on pathless paths. 
I donât know where exactly the borders of this would be, and Iâm sure there are small sections in between of higher difficulty that would have to be routed around. No âpathless pathâ for this pass exists, and I would delete it if there was one as the community norm in the Sierra Nevada is to not map pathless paths - having labeled waypoints of critical decision points is as far as most people go for XC terrain. I did move the pass location slightly since to be more accurate to my GPS survey of the two YDS Class 3 options (SAC T4) to gain the ridge that is otherwise SAC T5-6.
For Valor Pass I know of people that hiked up the ridge on the south side, then dropped as that is a little simpler. We felt perfectly comfortable doing a more direct approach, but stayed above cliff bands (which doesnât really show as well on opentopo, but with USGS or slope angle shading the map gets noisier for this purpose). This is a pretty vague representation based on my memory - and isnât entirely accurate as there might be some 2-3m cliffs or ledges etc that could pose a navigational hazard in the middle of that area.
This tells the story pretty well, but is probably a bit overkill and prone to small errors in terrain. In this case just having a node at the top of the pass seems fine to me, the rest doesnât have any needles that need to be threaded (aside from perhaps the chutes dropping from Valor lake to Ambition, but at some point you have to consider the route to the pass done).
