Terrain: The eastern part is considerably drier than the western part and is mostly unglaciated. It also seems to have higher ridges and and more of the higher peaks in the range (charted ones, anyway) - consistently over 2600m and 2550m with connecting ridges in the 2450-2500m range, compared to summits of 2500m and less in the western half of the range. Its valleys are noticeably much steeper and narrower than in the western half. There are many more high peaks in this area than can be listed in bivouac.com due to this site's restriction peaks under so many hundred metres of prominence. The peaks in the eastern Cayoosh are connected by long ridges that are not much less in elevation than the peaks themselves; as a result a great many high summits in this area are not documented here, although this is one of the higher areas of the Lillooet Ranges.
