Arapaho Lakes Trail Hike (2021.07.29)

Upper Arapaho Lake (2)

Upper Arapaho Lake 

James Peak Wilderness區內Forest Lakes南邊有一處被Forest Service放棄的湖區~ Arapaho Lakes,所謂被放棄並不是政策性的封山禁止攀登,而是主管單位不再維修此步道而不鼓勵山友攀登,但是還是有蠻多山友活動的。

Arapaho Lakes 從地圖上看是三個湖群,最東邊的兩個小湖海拔約10,778/3,285公尺,稱之為Lower Arapaho Lakes,最西邊的小湖海拔約11,470/3,496公尺,稱之為Upper Arapaho Lake,但這兩個湖群少人提及,一般登山客僅到中間的兩個湖,這兩個湖是連在一起的,中間只隔一寬約10公尺的陸地,第一個湖()比第二個湖(西)大很多,這兩座湖我在2010年即攀登過,今天除再度攀登此兩湖外,打算順便攀登UpperLower兩湖區三小湖。

岔路不明顯且以數根倒木橫擋岔路口,岔路再前行十餘公尺有一座原木橋,我捨此岔路續沿Forest Lakes Trail往上行。

取左不明顯岔路下行。

 

岔路下行30公尺遇左岔路,該岔路即是第一處岔路上來的路徑,還蠻清楚的;取右上行,小徑左側是Arapaho Creek,登山小徑蠻清楚的,應蠻多登山客在利用。

沿著Arapaho Creek(西)岸上攀,山徑轉為極陡爬升。

10:35 路過一棵大枯木後已達Lower Arapaho Lakes等高線,看左側林中植被還蠻乾淨的,決定由此左切往Lower Arapaho Lakes,座標N39.90963° W105.67230°,海拔10,715/3,266公尺,距登山口3.36/5.4公里;

在出水口小休和一位德裔美國山友寒暄後他要翻越南稜下Crater Lakes,我則沿Arapaho Lake的北稜攀登Upper Arapaho Lake

Arapaho Lake的北稜基本上還算好走,但有一段路是穿梭在針葉林的矮樹叢間是較困擾的,注意腳下別踩空了。

12:28 登上Arapaho Lake 北稜一處大亂石堆高點,俯瞰Arapaho LakeUpper Arapaho Lake則隱藏在西邊不遠處山腳下,中間要下到一小鞍部再攀上一岩坡;小心在大岩塊間朝Upper Arapaho Lake續行。

13:05 啟程下山,先下到Upper Arapaho Lake東岸走一趟後觀察下切West Arapaho Lake的路線,發現沿著Upper Arapaho Lake出水口下切應為可行,路徑雖然陡峭但依稀可看到不明顯路跡,顯示有山友由此線上下。

大岩壁峭壁段手腳並用、踏穩腳步再行亦不太困難,沿途沼澤型態百花齊放。

15:11 回到Forest Lakes & Arapaho Lakes 岔路前約30公尺的岔路,座標N39.90726° W105.66126°;早上是從左岔下來,但右岔路跡很明顯,取右岔沿Arapaho Creek左岸下行。

15:17 接回Forest Lakes Trail,座標N39.90609° W105.65943°,海拔10,125/3,086公尺;岔路口上行幾公尺即是一座原木橋,岔路口以倒木橫置極不明顯,取右循Forest Lakes Trail下山。

15:46 返抵Forest Lakes & South Boulder Creek Trail 岔路,取左岔下山。

16:14 返抵登山口,完成Arapaho Lakes 探索之行。
