ヨセミテの東、イースタンシエラのホワイトマウンテン周辺に生息する「ブリッスルコーン・パイン」という樹種は地球上で最も長生きと言われていて、「Methuselah」と名づけられた木は4781歳であると確認されています。一見「枯れ木」のようにも見え、ゆっくりとした成長をするこの木も、気温上昇の影響を受けて、近年の年輪が太くなっていることが確認されています。

Big Meadow Fire Update

件の山火事ですが「Big Meadow Fire」と名付けられています。
YAから最新情報が来ましたので転載します。(とりあえず英語)

The Big Meadow Fire that started near Foresta is now 55% contained according to reports this morning. The fire is approximately 2 miles east of El Portal and has burned almost 5000 acres. Except for the Big Oak Flat Road between Crane Flat and the intersection with the El Portal Road, Yosemite National Park is open and as majestic as ever. The Association offices in El Portal, which were evacuated Friday evening, are now open. The residences in old El Portal and Foresta are still evacuated as the firefighters work to control the fire.
The National Park Service this morning (Monday, 8:00 am) reported that “the fire continues to burn actively ( a large column of smoke was visible yesterday) in the wildneress towards Tioga Road near Tamarack Flat and northwest in Upper Crane Creek drainage. Today, firefighters will continue to aggressively build indirect fire line away from the fires edge. The strategy is to use indirect fire line along with opportunities to conduct burnout operations (when conditions safely permit) to stop the forward progress of the fire. Firefighters will also continue to reinforce fire lines east of El Portal and around Foresta. No major fire activity was reported in these areas.
Due to fire operations, the Tioga Road between Crane Flat and White Wolf
may close or access may be limited at any time today. Visitors on the east side can access Tuolumne Meadows, Olmsted Point, and White Wolf. However, through travel may be limited or restricted at any time.” For more detailed information please visit the Big Meadow Fire Website, http://www.inciweb.org/incident/1869/

Webcamによる観察だけですが、此処1?2日で、Valleyに入り込む煙がかなり減りました。
