Great climbing photo! I always wanted climb that wall, but alas, I aged out of technical climbing before I got to it. Now I am just another old ex-climber who backpacks.
Yes, it is some work to figure out walking distances, but not as hard as you would think. Sorry, I did not mean to be so critical. I was working on the update of my guidebook, and being in the thick of it, doing exactly what everyone says is to hard to do, I probably over-reacted. I have built a database for the Wind Rivers with over 1000 travel segments, each with miles, elevation gains and losses and a travel time estimate. Now I can just make any route by mixing the segments that and in less than half an hour get distances and time estimates. It is a "bite-the-bullet" thing to build the database, but once done it is really magic!
I am gradually building a similar database on the Sierra, but it lags behind my Wind River database. I was just saying that once your computer program narrows down the choices, it really is not that hard to go onto a program like TOPO and draw a line, with the distance. Just separate the trail portion and off-trail portion to get a rough time estimate. It really works quite well.
