[3] This year is noted for an especially long weather window of 11 days straight of calm, which reduced crowding at the high base camps.
[5] This broke the previous record for total summits in year from which was 667 in 2013, and one factor that aided in this was an especially long and clear weather window of 11 days during the critical spring climbing season.
[13] It used to be a 40-foot (12-meter) climbing face below the summit, with clear reports in previous years that there was a lot of snow, making it harder to determine what had happened.
[13] Nepal honoured several mountain climbers, including those that summited Everest in the 1970s and went on to conduct humanitarian projects in the impoverished land-locked country.
[14] Climbers honoured by Nepal included Wolfgang Nairz, Oswald Ölz, Peter Habeler, Raimund Magreiter, Robert Schauer, Hanns Schell and Helmuth Hagner.
[17] A group of chefs planned a seven course meal featuring local ingredients, and one of the challenges of serving gourmet food at high altitude is that people's sense of taste is altered.
[19][20] This group paves the way for more climbers to reach from the Nepal side of the mountain, and 346 permits were granted for this year in the climbing season which runs in the spring from April to the end of May.
[23] About 5 people are reported to have died or gone missing mountaineering at Mount Everest by late May 2018, including Nobukazu Kuriki, Gjeorgi Petkov, Rustem Amirov, and Lama Babu Sherpa.
This was televised and published as a book, as also was the ascent and summit of Ant Middleton with Ed Wardle, coincidentally taking place at the same time.
