Yo great job on the exploration, in my thread i mentioned i couldn't get over these mountains but maybe could with nitro boots :P
surprisingly the same place i was thinking of using them was where u climbed^^
Your method does show a path which may not be as easily accomplished my a non mage class. But u could always use the first steps in my guide

then after ontop with the help of a slow fall mechanic e.g. noggenfogger, parachute cloak etc follow your climb.
