山岳簡介:
La Plata Peak海拔14,336(4,370公尺),科羅拉多排名第5高的高山,座落在Sawatch Range;此座山的特點是他那崎嶇粗獷的北面斜坡,和它那長達2哩的東北稜經典技術攀岩路線Ellingwood Ridge (為紀念Albert Ellingwood而命名,他是一位洛磯山脈技術攀岩的先驅,也是第一位征服這個山脊的人)。紀錄上首次登頂此山的是The Hayden Survey Team,此探測隊於1873726日首次登頂,同時將此山命名為La PlataLa Plata一辭在西班牙語的意思是「銀」,因為在此區域當年蘊藏很豐富的銀礦而得名。附近的WinfieldHamilton20世紀初重要的採礦小鎮,如今已成廢墟鬼城(Ghost town)
La Plata Peak高聳矗立在Twin LakesIndependence Pass之間,四面都是陡峭的坡面,只有兩條較寬廣緩坡的山脊通向山頂。一條是Southwest Ridge,登山口在West Winfield Trailhead;另一條是今日一般登山客攻頂的標準傳統路線Northwest Ridge,登山口是La Plata Peak Trailhead,就在CO 82公路旁(距東邊的Balltown 14.5哩,距西邊的Independence Pass 8.8)
此座山我在2007.07.21和山友GoergeThomas完成首登,上週六在山友宇靈兄的邀約下二度前往攀登,同行者還有阿才、佳欣兩位山友,當天我於凌晨02:20從女兒家出發,03:00GoldenJefferson County Building parking lot會合後共乘宇靈兄的車子出發。

行車資訊:
開車由Golden取道I-70州際道路西行,行約65哩在Exit 195下交流道改走CO-91南下,22.1哩後經過小鎮Leadville匯入US 24續往南行,US 24南行約16.2哩後右轉CO-82西行,途中經過Twin LakesCO-82計行約14.5哩後於05:00左右抵達道路左側La Plata Trailhead,登山口有一處不算大的土石地面停車場。

步程簡述:
05:10 天未亮,我們戴頭燈從登山口出發;

沿停車場東端可行車的土石道路82C (South Fork Lake Creek road)南下,隨即從South Fork Lake Creek的橋上經過後沿車道續行。

05:17 脫離82C (South Fork Lake Creek road)取左入林,此處為La Plata Peak Northwest Ridge登山路線的登山口,海拔10,150/3,094公尺,距登山口約0.25哩;

進入林間是羊腸小徑,天黑不是看得很清楚,偶而要詳細辨識一下正確路徑再前進。
05: 23 經過一座小橋,天黑看不見橋下狀況,記得上次來時橋下是黃濁的South Fork Lake Creek,水勢澎湃,從陡峭的峽谷中穿過,有點「小」峽谷的架勢;此處海拔10,120/3,085公尺,距登山口約0.4哩;

步道在過橋後上一段小坡隨即朝東在松林間緩下坡東行。


05:36 來到La Plata Gulch小溪,經幾根倒木跨越小溪,此處海拔10,146/3,093公尺,距登山口約1.0哩;

過溪後隨即轉向南,一路沿La Plata Gulch上行,路右潺潺流水聲一路相伴。此段路大約在海拔10,400呎到10,700呎之間,整個步道大部份是圓木或石塊築成的石階,坡度有點陡,速度稍微加快便氣喘如牛。
06:23 出森林,海拔11,000/3,353公尺,距登山口約1.9哩;路徑轉為平坦,仍在La Plata Gulch中前行。

06:32 步道往左切上一處岩石坡離開La Plata Gulch,此時海拔13,743 呎的Sayres Benchmark出現在山谷遠方盡頭,此地海拔11,065/3,373公尺,距登山口約2.3哩;

步道在碎石坡中沿山坡緩升,偶而穿過稀疏的松林,離峽谷越來越高。

06:55 來到一凹谷地形,步道90度左轉;往上一看是數不清的“之字形坡道,此地海拔約11,462/3,494公尺,距登山口約2.6哩。

07:16 上到“之字形坡道頂點,步道轉直,朝南沿山腰緩升,此處海拔約11,880/3,597公尺,距登山口約2.8哩;

朝南緩升的側坡小徑路面細石鬆散易滑,右側是直洩谷底的土、岩石坡,下山時要特別小心。
07:48 上到一處稍平坦地形,一塊大約6x6呎的巨石在路徑左側,此地海拔約12,421/3,786公尺,距登山口約3.4哩。

登山小徑在巨石處右轉再行一小段路後步道旋即轉左,朝Northwest Ridge陡上,海拔約12,480/3,804公尺。

08:14 在岩石坡間經一段陡攀後抵Northwest Ridge稜線,海拔約12,742/3,884公尺,距登山口約3.6哩;
The trail reaches the northwest ridge at 3.6 miles (12,740 ft.

此處展望佳,東側下方是La Plata Basin,後面山勢崢嶸的稜線即是登La Plata Peak的攀岩路線Ellingwood Ridge,北望科羅拉多的最高峰(Mount Elbert)與次高峰(Mount Massive)已在群峰中冒出山頭。

此地距山頂還有1.25哩左右,但卻是此行較為艱難的一段路程,稍事休息後順稜線爬升,在正前方有險惡高點無法直攻,步道從右(西)側坡繞過,時而在亂石堆中穿梭攀爬,挺累人的!

此後步道即沿著稜線上攀,但路徑很分歧,必須靠登山者自行研判要攀爬的路線。

鞍部西南不遠處有一座小山頭,鞍部往西南另有一條登山步道是La Plata Peak的另一條登山路線Southwest Ridge Trail,下山時在此要特別注意,不要走錯了!步道轉左朝山頂直上。

13:42 下抵6x6呎的巨石處,海拔12,421/3,786公尺,步道左彎下一段小坡後右彎朝西北下行,此段下坡路砂石異常鬆散易滑,小心移動腳步,速度不會比上山快多少。
