( CNN ) -- Call it the Treaty of Everest 2013 . It 's a two-paragraph agreement , in both English and Nepalese , signed by climbers and Sherpas who on Saturday engaged in a donnybrook at 23,000 feet . Punches , kicks and even rocks were thrown , according to a statement posted Sunday on the website of one of the climbers , Simone Moro . The Sherpas , locals who guide expeditions up the world 's highest mountain , apparently became angered when the climbers from Italy , Switzerland and the United Kingdom did not listen to instructions from the Sherpas , moved above them on the peak and dislodged ice that fell in the direction of the Sherpas . At one point `` the climbers ... were told that if they were n't gone in one hour that they would all be killed , '' the statement said . But by Tuesday , both sides agreed to climb nice and put it in writing . `` Both parties have realized their errors and apologized to each other in front of those present , '' says handwritten note obtained by CNN from the Nepal Mountaineering Association . `` Both parties agreed to help each other in the future to make successful each others goals . '' The agreement bears at least 28 signatures , though some appear to have been repeated . No matter the exact number , their resolve against conflict seems certain . `` All those present agreed and committed that such activities by anyone in the mountaineering and in the tourism sector , '' it says . So maybe that will end what one post on Adventure Journal 's website described as `` an inauspicious start to the spring climbing season on Mt . Everest . '' In another post , a guide said mistakes were probably made on both sides . `` Everest is a mountain where people pour an incredible amount of passion and money into their efforts . This is true for professional and recreational climbers , and for Sherpa who earn most or all of their family 's annual income in these two months on the mountain , '' guide Adrian Ballinger wrote . `` The constant pressure to break records , attempt new routes , and be the strongest , whether for personal pride , sponsors , future job offers , or media , can cloud the purity of our climbing here . And these pressures can lead to disagreements , arguments , and hurt feelings . But none of these pressures should be allowed to lead to violence , or to breaking the essential bonds that tie climbers to each other , '' Ballinger added . But one of the climbers involved in the incident who signed the agreement told Britain 's Telegraph newspaper that money has changed the Everest experience and spawned resentment among Sherpas . `` They 're angry at this financial gap on their mountain , '' Jonathan Griffith said of the Sherpas . `` These commercial trips are based on a lot of luxury and getting you up the mountain and a lot of these Western clients do n't even know what the names of their Sherpas are . '' And that , he says , makes him wonder if he 'll try Everest again , the Telegraph reported . `` I did n't think the main danger would be a mob of Sherpas throwing rocks , '' Griffith is quoted as saying . CNN 's Manesh Shrestha and Catherine E. Shoichet contributed to this report .
Fight erupted Saturday between climbers and their guides . Handwritten agreement pledges no more fights on mountain . Climber says money , Western attitudes anger Sherpas .
