The summit of Everest has been described as "the size of a dining room table".<ref>{{cite web|url=http://www.swindonadvertiser.co.uk/news/local/9046854.Swindon_explorer_on_top_of_the_world/|title=Swindon explorer on top of the world|website=Swindon Advertiser|date=25 May 2011|access-date=20 September 2015|archive-date=28 August 2018|archive-url=https://web.archive.org/web/20180828221322/http://www.swindonadvertiser.co.uk/news/local/9046854.Swindon_explorer_on_top_of_the_world/|url-status=live}}</ref> The summit is capped with snow over ice over rock, and the layer of snow varies from year to year.<ref name=sci>{{cite web|url=http://www.extremescience.com/everest.htm|title=Highest Mountain – Everest|website=extremescience.com|access-date=20 September 2015|archive-date=7 September 2021|archive-url=https://web.archive.org/web/20210907150557/http://www.extremescience.com/everest.htm|url-status=live}}</ref> The rock summit is made of Ordovician [[limestone]] and is a low-grade metamorphic rock.<ref>{{cite web |url=http://www.montana.edu/everest/facts/morefacts/ff06.htm |title=Montana State University – Everest Education Expedition – Everest Facts |publisher=Montana.edu |access-date=17 June 2016 |archive-url=https://web.archive.org/web/20160305013250/http://www.montana.edu/everest/facts/morefacts/ff06.htm |archive-date=5 March 2016 |url-status=dead}}</ref> (See the [[#Surveys|Surveys]] section for more on its height and about the Everest rock summit.)

Below the summit, there is an area known as "rainbow valley", filled with dead bodies still wearing brightly coloured winter gear. Down to about {{convert|8000|m|ft|abbr=on}} is an area commonly called the "death zone", due to the high danger and low oxygen because of the low pressure.<ref name=dz/>

Below the summit the mountain slopes downward to the three main sides, or faces, of Mount Everest: the [[North Face (Everest)|North Face]], the Southwest Face, and the East/[[Kangshung Face]].<ref name="facts">{{cite web|url=http://www.everest1953.co.uk/Facts.php |title=Everest Facts |url-status=dead |archive-url=https://web.archive.org/web/20150509045702/http://www.everest1953.co.uk/Facts.php |archive-date=9 May 2015}}</ref>{{Better source needed|date=February 2021|reason=According to this website's 'About' page, this is a person website run by a fan of Everest expeditions and therefore does not constitute a reliable source.}}
