【美國加州 Yosemite National Park】優勝美地國家公園健行之一.迷人的秋日美景。飽覽山谷與Vernal Falls、Nevada Falls兩大瀑布

「一生必去」這4個字的最高等級用語,絕對可以用來形容美國加州的「優勝美地國家公園」(Yosemite National Park),相信沒有人會反對。因為它在世界上的地位,彷彿就是「大自然的大教堂」。
優勝美地國家公園(Yosemite National Park),是美國國家公園內極為閃耀的一顆明珠,地處加州東北部,內華達山脈的西麓,曾是印第安原住民阿瓦尼奇人(Ahwahneechee)的故鄉。公園的範圍橫跨加州中西部圖奧勒米縣(Tuolumne)、馬里波薩縣(Mariposa)和馬德拉縣(Madera)。優勝美地國家公園於於1984年被納入聯合國教科文組織(UNESCO)世界遺產,每年吸引4百萬來自世界各地的遊客前來觀光。
優勝美地國家公園內,有超過95%的土地被指定為原生地域(wilderness),為了要保護公園的原貌,美國總統林肯於1864年6月30日,將優勝美地谷蝴蝶林(Mariposa)內的美洲衫巨木林,設為美國的第一座州立公園。並且在「國家公園之父」約翰•繆爾(John Muir,1838~1914)這位作家、科學家、保育先知的倡議之下,於1890年成為第二座國家公園。它幾乎是全美甚至全球最受歡迎的國家公園。
公園內除了有四面絕壁的優勝美地山谷,還有充滿高山美景的圖奧勒米牧場,自然風光令人歎為觀止。而它的美和大遠遠超過一般人所暸解,公園的佔地面積超過1,169平方英哩/284,899 公頃,而其中最多遊客造訪的的優勝美地谷(Yosemite Valley),只佔了整個公園不到1%的面積。優勝美地國家公園主要有四大景區,呈F型分佈,分別是優勝美地谷(Yosemite Valley)、山頂的冰川點(Gracier Point)、北側的第奧嘉(Tioga Pass)以及南端的瓦沃納(Wawona)景區。這次的優勝美地之旅,只有北側的第奧嘉景區沒有造訪,那裡就留待下次不同季節再去造訪吧!

優勝美地山谷在上一次冰河時期被冰川覆蓋,山谷呈U字型,兩旁峭壁上到處可見由冰川切削過的痕跡,其中最有名的就是半圓頂(Half Dome),這顆巨岩是冰河時期所形成的,峰頂海拔2,693公尺,歷時8,700萬年,在地質與歷史上他就是個不折不扣的巨人。只要你在優勝美地國家公園內,走到比較高的地點,幾乎從任何地方,都可以看到它的身影,據說 North Face 品牌 logo 的…
