Abstract: Quaternary glacial vestiges in the Western Hills,Beijing Municipality,have been investigated and studied from the 1950s on.However,since the 1980s,divergent views on the related palaeoglacial phenomena have been put forward by some geographers and geologists,whose main viewpoint is that the occurrence of the phenomena concerned can be explained by the nivation and solifluction in the periglacial climate.In this trip,the macroscopic and microcosmic features of the Quaternary glacial vestiges that are the key to judging and to understanding wheter the palaeoglaciers were developed in the following five visited localities:glacial pavement at Moshikou,Quintuoling till of the Guantuoing glaciation on the Guantuo Ridge,till of the Zhaojiatai glaciation in the west of Taipingzhuang,the glaciofluvial deposits of the Zhaojiatai glaciation in the north of Lujiatan Township and till of the Guantuoling glaciation in the east of Dafuzhuang.
