good question, not weird at all, I do the same in studying terrain maps from routes I've explore (or will). The red route you marked is the common exit from loader peak and eactually quite a good one. Its steep, but no bad cliffs or drops. I've done it before, which led me to think I could then also try the gully just south of loader, but still north of door jamb. The second blue streem on your map. Right down at the V, it had the drops we faced even though it didn't look quite as bad as the northern common route. However. haha.

Good idea on the 8mm rope, my buddy has an older climbing rope he's planning to upgrade, so we are going to cut a couple emergency sections from that to use/carry on questionable routes (and to get to/from caves of course that HAVE to be explored, haha)
