There’s a good documentary on amazon (and I think also apple) called Death Zone: Cleaning Mount Everest, inside one of the earlier all-sherpa high level cleanups. It’s almost all fly on the wall footage filmed by the sherpas with gopros they learn how to use on the way, so it’s excellently rough and ready and gives you loads of views and access that you’d not normally see. The messaging is both OTT and fake which is annoying, the real story is definitely more than enough, but it didn’t take away from the reality of it for me. It shows really well both how bloody disgusting some of the climb areas are especially the camps, but also does a really evenhanded job of showing how that happens- I was just starting to get really irate at what looked like totally careless dumping then a storm comes in and blows everything to ****, frinstance. And it shows how hard it is to recover a beer can let alone a body. It’s made extra sad and poignant as the lead sherpa died on the mountain not long after
Left me thinking “sod the bodies, clean up the junk” though. And also, quite a lot, “isn’t it pretty routine now to fly helicopters to camp 2, some climbers use it to shorcut the return leg? Why are they having to haul literal tons of crap down the khumbu?”. The restrictions on flight are mostly artificial and get waived pretty damn fast when they have a short season and the outfitters want to build the lines faster. Though in fairness I think they’re experimenting now with cargo drones.
