This hike would involve substantial elevation gain. That would concern me, too, not only because it makes the mind-bending hike more strenuous, but because some people cannot tolerate elevation. Maybe if they have several days to acclimate, but otherwise they might get into trouble.
A few years ago, I camped and then I drove through Rocky Mountain National Park and up that extreme pass. Maybe Iceberg? I was by myself. I got to the top and jumped out to go to the Visitor Center. One step, and I almost passed out. Absolutely splitting headache. I thought I would throw up. I was shockingly dizzy. I had the wherewithal to realize that it was altitude, and LE would almost certainly not let me drive if I passed out in the parking lot. I immediately jumped back in the car, and headed down the mountain. My head began to clear in a mile or so. About 2,000 feet lower and no more headache, but I was super freaked out.
So, yes, I do wonder if a hiker out of Logan Pass could get suddenly incapacitated by altitude.
PS Nothing would possess me to ever go back to RMNP. Every moment was misery for me, including the camping. I’d love to explore Glacier, though. At the foot of the mountains lol.
