Hiking route
上週六和登山隊前去Guanella Pass附近的Silver Dollar Lake健行，因天氣欠佳，冒雨登上Silver Dollar Lake和Murry Lake後匆忙下山；領隊品菁女士曾詢及由Murry Lake攀登Argentine Peak的可行性，上網查了一下資料發覺是可行的，而且有多數登山客是採取Square Top~Argentine~Wilcox loop的O形環走方式，但中間有一段路是必須經過Naylor Lake的私人領域，那是一種非法行為，我利用本週一大晴天特地前往一探路況。
為了避開侵入Naylor Lake的私人領域我採取由Silver Dollar Lake Trailhead起登，到Murry Lake後先攀登Mount Wilcox，然後沿Wilcox~ Argentine稜線攀登Argentine，之後再沿Argentine南稜下到Argentine~Square Top鞍部，屆時視時間及體力決定進一步行程，要是時間及體力許可下續登Square Top Mountain後原路回到Argentine~Square Top鞍部，然後向東下切回到Murry Lake接上Silver Dollar Lake Trail回到登山口；如果時間或體力不許可則行至Argentine~Square Top鞍部後捨去攀登Square Top Mountain隨即下切回登山口，反正Square Top Mountain在十多年前即已攀登過了！
本文圖片有團體照之照片是上週六和登山隊去健行的照片，因路線相同加之當天天候不佳拍照不多，當天行程不再另寫紀錄，特將當天團體照張貼在今天的紀錄中。

行車資訊：
從丹佛沿I-70州際公路西行，在Exit 228下交流道進入小鎮Georgetown，然後一路沿“Guanella Pass”南行；9.5哩抵Guanella Pass Campground，再行0.1哩遇右岔Naylor Lake Road，右轉Naylor Lake Road立即抵達Silver Dollar and Murray Lake第一登山口，小車停此，但車位很少(六七部左右)，在右轉Naylor Lake Road之前道路左側另有一較大停車場。四傳車輛可沿Naylor Lake Road土石路續行0.7哩抵達第二停車場。
步程簡述：
08:10 第一登山口出發，海拔約10,880呎(3,316公尺)；

沿著Naylor Lake Road西行，一開始路有點陡，沿路林間幾處營地有人在露營。
08:30 抵達第二登山口，海拔約11,200呎(3,414公尺)，距第一登山口約0.7哩，路旁空地蠻大的，可停不少車子；道路續行通往Naylor Lake，那是一座私人湖泊勿進，Silver Dollar and Murry Lake第二登山口左岔小徑上山。

小徑先在松林間穿行一陣子後便穿越森林線，一路在Square Top Mountain北坡下爬升，偶而是岩石坡，偶而是高可及腰的willow樹叢，沿途俯瞰右側山坡下的私人湖泊Naylor Lake；

09:30 抵達第一個湖泊Silver Dollar Lake，海拔 11,950呎(3,642公尺)，距第一登山口約2.5哩，她安詳的躺臥在海拔13,794呎(4,204公尺)的Square Top Mountain北坡下；

休息拍照後續往Murry Lake，Murry Lake距Silver Dollar Lake約有半哩路，爬升約250呎，從Silver Dollar Lake的北岸沿小徑稍往西北爬升，沒多久即抵達Silver Dollar Lake的北岸稜線，海拔約12,200呎(3,719公尺)，Murry Lake就在北邊幾十呎的稜線下。

10:05 下抵Murry Lake，海拔12,150呎(3,703公尺)，距第一登山口約3.0哩；

此湖比Silver Dollar Lake小了一點；在此觀察一下上Mount Wilcox的路線後取右下行，然後由一條乾溪溝上攀到Mount Wilcox南坡下谷地，由Murry Lake上到Mount Wilcox一路無明顯路跡，全得靠自行研判行進路線。

10:30 上到Mount Wilcox南面山坡下山谷凹地，山谷凹地長滿矮柳樹叢(willows)，觀察一下上Mount Wilcox西南稜的路線後先沿柳樹叢左側上行，行約數十公尺再右切穿過柳樹叢。

10:35 穿過柳樹叢(willows)到Mount Wilcox山腳下朝Mount Wilcox和Argentine Peak間的鞍部爬升，這段路毫無路跡，全靠登山者自行判斷路線上攀；如果越取左往低鞍上切，到稜線後再右轉沿Mount Wilcox西南稜登頂距離較長，但坡度較緩，如果越取右往稜線上切，到稜線後再右轉沿Mount Wilcox西南稜登頂距離較短，但坡度較陡峭，我則依自己事先規劃的路線往上爬升。

11:15 登上Mount Wilcox西南稜稜線，此處海拔約12,960呎/ 3,950公尺，距登山口約3.78哩/6.05公里；在稜線上東望Mount Evans、Mount Bierstadt兩座14ers，西眺待會兒要去攀登的Argentine Peak和遠方的兩座14ers~Grays & Torreys Peaks；

Mount Wilcox是全科羅拉多排名第315的高山，也是全科羅拉多州排名第262名的13ers (海拔介於13,000呎~13,999呎之高山總稱)，今天天氣良好，山頂有360度的展望，只可惜最近全美各地的森林大火影響空氣品質，視線不是很清晰。

12:00 下山，循原路下山前往Argentine Peak，規劃路線是沿Mount Wilcox西南稜下到Mount Wilcox/Argentine Peak間鞍部後再沿Argentine Peak東南稜上到Argentine Peak山頂。
12:38 下到Mount Wilcox/Argentine Peak間鞍部最低鞍，海拔約12,900呎/3,932 公尺，距登山口約4.77哩/7.68公里。

從最低鞍沿Argentine Peak東南稜朝西北方往Argentine Peak山頂爬升，這一段路比較陡峭難爬，中途會由高壓輸電鐵塔下經過，接近Argentine Peak山頂時由於右側稜線陡峭險峻，必須向右腰繞避過陡峭險峻路段。

13:40 上抵Argentine Peak山頂東南面寬平的苔原帶，繼續沿西北方朝山頂前進，山頂立有一根大陸分水嶺步道( Continental Divide National Scenic Trail )的木樁，目標明顯。

13:45 登上Argentine Peak山頂；Argentine Peak山頂海拔 13,738 呎/4,187 公尺，距登山口約5.7哩/9.12公里；Argentine Peak是全科羅拉多排名第131的高山，也是全科羅拉多州排名第78名的13ers (海拔介於13,000呎~13,999呎之高山總稱)，山頂岩石上崁有一枚毀損僅剩一半的水準點(benchmark)；

14:30 下山，計畫沿著Argentine Peak的南稜下到Argentine Peak/Square Top Mountain間的鞍部後看情況續上Square Top Mountain或左切下山。

14:50 抵達Argentine Peak南稜13,550呎山頭，在此西南俯瞰前兩週才去攀登的高山湖Shelf Lake及其後面的Decatur Mountain；

15:10 下抵Argentine Peak/Square Top Mountain間的最低鞍部，海拔 13,990 呎/3,959公尺，距登山口約6.7哩/10.2公里；

此處如要繼續攀登Square Top Mountain還有1.3公里的距離，必須再爬升約250公尺，來回估計還要一、兩個小時，恐怕下山太晚，況且該山我於十多年前即已攀登過，所以捨該山取左下切往Murry Lake移動，打算下抵Murry Lake的南岸稜線後接到Silver Dollar Lake Trail循早上上山的步道下山。

15:49 下抵Murry Lake的南岸稜線後接到Silver Dollar Lake Trail右轉下山；由Argentine Peak/Square Top Mountain間的最低鞍部到此約1.13哩。
17:10 返抵登山口停車場，完成一趟兩座13ers的小O環走，如果早些出門再加上攀登Square Top Mountain來個三山小O環走不是太難的行程！
