Hmmm, that’s a good question, and I’m not sure why I didn’t think of it. There is something similar, though Daumal’s book focuses more strongly on the individual than society; are there political overtones there? I’m tempted to re-read. It’s tempting to say that there’s no character development in Lesabéndio, except in an extremely overt way: when one of the characters absorbs another (as Lesabéndio does repeatedly), the absorber takes on some of the absorbed’s qualities. And Lesabéndio does become one with the planet, but that’s not so much seen as personal development but more the inhabitants achieving their collective destiny. 

I don’t know German mountain-climbing literature very well (aside from Adalbert Stifter’s Rock Crystal and Riefenstahl’s The Blue Light, but I suspect that there are probably more commonalities there? But Mount Analogue isn’t that far off.
