I follow the happenings on Everest on an annual basis, pretty much every year since the 1996 debacle (see Into Thin Air [book not the movie] by Jon Krakauer).
The best source I've found for intelligent coverage is the blog of Alan Arnette:
http://www.alanarnette.com/everest/everest.phpAlan will be issuing his final commentary soon but in the meantime this post from a couple of days ago provides a summary of the issues encountered this season.
http://www.alanarnette.com/blog/2019/05 ... he-crowds/While the crowds and in particular the now famous image by Nims Purja looking up from the Hillary Step are blamed for most of the issues this year the truth is not so simple. While it's true that the sheer numbers hit a new record this year the problems are more related to the very adverse weather conditions and the great increase in the number of inexperienced an/or unprepared climbers combined with the rise of "budget" outfitters who promise a lot for a little and often fail to deliver the clear thinking and organizational skills needed to be successful on the 8000 metre peaks.
It should be noted that in addition to the 11 deaths on Everest there were another 10 on the other 8000m peaks in the area and in those cases crowds did not come into play at all. Most deaths this years were related to altitude sickness and bad weather. The crowding on Everest itself was less due to sheer numbers than to the fact that the poorly prepared just move too slowly and their outfitters/guides are just too hesitant to insist that those who are getting into trouble turn around.
Of the 11 Everest deaths, 6 occurred after a successful summit, of the 21 in the area only 4 were closely related to crowding which caused the summit bids to extend from a "normal" 10 - 12 hours up to as long as 20 hours. that combined with extended periods at the high camps waiting for a break in the weather resulted in a number of altitude illness deaths.
It's not just paying clients anymore, the number of sherpas required and the fact that many of the most experienced are now working in other areas (Denali in the US for example) means that along with inexperienced clients the quality of the support is not at the level it once was.
