My BS detector is at a very low level. Initially Mueller and the others may have put on a strong face, understating the challenges and saying it was an enjoyable adventure. But in reality they struggled and came near freezing to death. In Mueller's reported account he admits a couple times that they were "fortunate." Yes, they were very fortunate to reach Mr. Colby that second day. But I suspect also that they had a map and knew Colby was nearby. Perhaps this knowledge, and the lack of provisions, prompted them to beat feet down the canyon, out of the wind and toward hope. I'm sure they also needed water and so remained in the creek as long as possible.
I don't follow your skepticism. Why do most people make a fire and eat food when they are trying to survive? I do find it curious that they only had one match, but that's explained in Brouwer's article. Matches weren't allowed near the hydrogen-filled balloon. The threat of exploding was also why they didn't land at Camp Sierra, where Mueller saw campfires burning.They lite a fire(why?). They ate 1/3 the food....hmm.
More like 24 hours. They landed in the afternoon/evening of the first day and reached Colby in the afternoon/evening of the second day.Finally they get the the end...having gone 1/2 a mile in 2 days.
Also, if they landed in the flat area near the top of Grotto Creek, it would have been approximately a 2.5 or 3-mile trek down canyon then around and up to Colby Ranch. If they landed on the shoulder of Strawberry, it would have been a little longer--and probably much tougher. So my guess is they landed somewhere around 5200' right next to Grotto Creek. According to the topo, there is a relatively flat section of ridgeline there, maybe 400 feet long and 475 feet at its widest.
Considering the extreme XC travel, low provisions, poor gear, and group pace, I'm not surprised it took them 24 hours to find Colby.
Perhaps it was a tiered waterfall, and they could only see the top tier. Or maybe they couldn't see the entire drop but knew it was too much to downclimb.30 or 50ft "fall". Wasnt it more 190ft..who came up with 30?
