丹佛地區華人登山隊相約於上週六(4)前去攀登Guanella Pass附近高山湖泊Shelf LakeShelf LakeArgentine Peak (13,734 ft/4,186 m)西南稜約2.1哩另一座高山Decatur Mountain (12,890 ft / 3,929 m)的東面山腳下,也就是介於Decatur MountainSquare Top Mountain (13,783 ft/4,201 m)之間的Smelter Gulch頂端,此湖之所以名為Shelf Lake可能是因其位在Decatur Mountain山腳下,而湖的位置正是山谷盡頭一突出的高處岩架上,所以以其所處位置地形命名之,湖的位置大約在Guanella Pass西邊四哩處。
當天參加人員有11人,除了住Aurora的徐先生自行開車前往外,我們從Golden分乘兩部高底盤四傳車前往登山口。

此湖之所以名為Shelf Lake可能是因其位在海拔12,890呎的Decatur Mountain山腳下,而湖的位置正是山谷盡頭一突出的高處岩架上,所以以其所處位置地形命名之,在Rocky Mountain National Park裡也有一座Shelf Lake,地形完全相同!
