Question: What is the name of the 350m high hill and Gustav Arthur Graser and his brother Karl Graser co-founded a social reform settlement?

<P0-S0> Pha Chor (Thai: ผาช่อ , rtgs: Pha Cho ) is a cliff located in Chiang Mai, Thailand, and is managed by Mae Wong National Park. <P0-S1>  Pha Chor is natural phenomena caused by an uplift of one of the Earth’s plates and also by erosion of wind and rain. <P0-S2>  Geologists believed that a hundred or a thousand years ago this area was a part of the Ping River by observing pebbles and stones that were distributed in this area until the Ping River changed its flow direction to another path and that made this area lift to high hill. <P0-S3>  Through erosion the high hill formed into a cliff. <P0-S4>  Pha Chor is a 30 meter high cliff that has a structure like a huge monolithic wall or Roman pillar. <P0-S5>  With unusual natural features that are similar to the Grand Canyon in The United States of America, it has caused Pha Chor to be known as the Grand Canyon of Thailand <SEP> <P1-S0> Monte Verità (literally Hill of Truth) is a hill (350 m high) in Ascona (Swiss canton of Ticino), which has served as the site of many different Utopian and cultural events and communities since the beginning of the twentieth century, having started out as a popular destination for Wandervogel hikers during the Lebensreform period. <SEP> <P2-S0> Gustav "Gusto" Arthur Gräser (16 February 1879 – 27 October 1958) was a German alternative lifestyle advocate, artist, and poet. <P2-S1>  He is considered one of the fonders of communal lifestyle in Germany. <P2-S2>  Together with his brother and fellow artist Karl Gräser, he co-founded one of the earliest social reform settlements, which was located along Monte Verità in Ascona. <P2-S3>  His penned and painted works included many of that were not published until a revival of interest during the counterculture of the 1960s emerged. <SEP> <P3-S0> Joseph Rowntree (24 May 1836 – 24 February 1925) was a Quaker philanthropist and businessman from York, England. <P3-S1>  Rowntree is perhaps best known for being a champion of social reform, partner and friend of Charles Booth, and his time as a chocolatier at family business "Rowntree's", one of the most important in Britain. <P3-S2>  Even as a powerful businessman, he was deeply interested in improving the quality of life of his employees; this led to him becoming a philanthropist, pursuing many charitable causes. <P3-S3>  In 1904 he created three trusts, the Joseph Rowntree Village Trust (JRVT) which was originally set up to build and manage the garden village of New Earswick, the Joseph Rowntree Charitable Trust (JRCT) and the Joseph Rowntree Social Services Trust (JRSST). <P3-S4>  The latter two were both set up to effect social reform, the difference between them being that whereas the Charitable Trust was set up as a charity, the Social Services Trust was set up as a limited company so that if necessary it would be able to undertake social and political work not legally allowed by a charitable Trust. <P3-S5>  He suggested that only the JRVT would be permanent but in fact all the trusts are still in existence although the Social Services Trust has changed its name to the Joseph Rowntree Reform Trust and with the separation of the Joseph Rowntree Housing Trust from the Village Trust in 1968, there are now four trusts that exist today.
