2006 Tioga Road除雪ログ

5月1日
* Tioga road progress May 1, 2006 - Today, we were able to begin the opening of Tioga Road. Crews made it to Gin Flat. Snow depth is approximately 5 feet and the snow is very wet and heavy. They found three trees buried in the snow, one of which was over 24" in diameter.
* Glacier Point road progress - No progress report was submitted for Glacier Point road which also started today.

5月2日
* Tioga road progress - May 2, 2006 Plowing operations have reached Big Meadow Overlook. The snow depth is now 7 feet with very dense snow. We have run in to 8 buried trees, some over 24 inches in diameter, that had to be removed so plowing could continue. Our hope is to reach South Fork by Thursday.
* Glacier Point road progress - May 2, 2006 One half mile from Badger Pass. Snow depth is approximately 7 feet. All is going well.

5月4日
* Tioga Road progress:
Ending location: At South Fork Bridge
Snow depth: 8 Feet
Very heavy snow pack, encountered 8 trees with average size of 18-24 inches. We are now at the first avalanche zone. We are expecting to plow through this first zone early in the morning. If the temps go up considerably, crews may be forced to come back West of the zone until the temps drop or the slope stabilizes.

* Glacier Point progress:
Ending location: .8 miles from Badger Pass
Snow depth: 7 feet
Slow progress with rotary due to snow depth and high water content.

5月5日
* Tioga Road:
Started at South Fork Bridge and ended in the middle of Avalanche zone 1. Snow depth is approximately 6 feet. Quite a bit of rock and trees down in the avalanche zone. Will continue through the zone tomorrow.
* Glacier Point Road:
Still under a mile from Badger. No progress today. Loader mounted rotary broke down and needs to be taken to the shop for repairs.

5月8日(朝の報告)
3マイル強も進んでいます。8,000ft.地点は地図からプロットしたものですが、White Wolfへの分岐のすぐ近くのようです。去年のペースを追い抜きそうです。

Tioga Roadは進まなかったようですが、GP Rd.はSentinel Domeが目の前です。あと0.3マイル弱も進めば、道路は一気にGPへと下り始めます。金曜には(とりあえずの)除雪が終了しそうです。

*Tioga Road progress:
Plowing operations have now gone 22.4 miles from Crane Flat. They are now going down toward Porcupine Campground. Snow depth is approximately 8 feet. They are now encountering more rocks in the snowpack and have had to remove two buried trees.

*Glacier Point:
They have reached Glacier Point. They are now in the progress of cleaning the parking lots, patching potholes, removing a large boulder from the road, ditching, and sweeping. Forestry crews are also working up on the road. There are quite a few trees that need to be removed along with brushing operations. The road will be open to administrative traffic Monday and barring any problems, should be open to the public by some time late next week.

May 21
Tioga road progress - May 21, 2006The road crews are about 1/2 mile from Olmstead.The following is the latest observation by the Avalanche Team.What's ahead Zones 10, 11, 12, and 13 should not be issues. Olmstead is and will continue to be a problem for sometime to come. We have accomplished only one explosives blackening op due to the continuing warm temperatures and high hazard. This operation was accomplished from above the slab with the use of ropes. It was very successful in removing a large area of concern but this process is pretty time consuming and there are many times this area of thick snow left to deal with. At this time it is uncertain if it will be safe for the crews to plow through when they get to Olmstead. The weather forecast calls for much cooler temperatures next week, so we may get a break for plowing and for blasting.

除雪はOlmsted Pt.に到達しています。明日の朝5時半、雪がしまり雪崩の可能性が無ければ、一気に除雪を試みるようです。27日にはヨセミテクリークまでの部分開通の可能性がありそうです。[註：うまくすれば、6月早めにTuolumneまで開通するかもしれません]
GPは25日（木曜）開通の予定。

108号の除雪状況にも要注意です。5月の第一週にSonora Passの麓(26.4 MI EAST OF STRAWBERRY )に達していました。連休前に峠が越えられるようになるかもしれません。

May 23
*Tioga Road:
Due to the high avalanche danger at Olmsted, the crews were not allowed to plow through this zone. Wednesday morning, they are going to attempt to plow through starting at 0530. If there is a good freeze up there tonight, they will be allowed to plow through the zone. Today, the crew worked at widening the road from White Wolf to Olmsted. We hope to have segment 2, from Walker Party to the Yosemite Creek Bridge, open to the public by Saturday May 27.

*Glacier Point road will be open to the public starting early Thursday, May 25th.

May 30
The crew is now at Tenaya Lake and is trying to go past the avalnche zone at Pywiack Dome. If they get through the may be in the meadows very soon.Glacier Point road is open.

May 31
除雪隊Tuolumne Meadowsの西端に到着。 Mono側は未だ除雪を開始していなかったようですね。
Olmsted Pt.の斜面は、未だ雪崩の危険があるようです。
The road crew is now up to the West end of Tuolumne Meadows. Snow depth is approximately 4 feet. Mono County is scheduled to start plowing into the park June 1st. Olmsted avalanche zone is still a very active and dangerous avalanche threat. (J. Cyr - 5/31/06)

June 1
雪崩危険地帯の状況が開通日を決めそうです。やはり17日付近でしょうか。
Today, the road crew will be going through the Dana Meadow avalanche zone. Once this is completed, the road will have been plowed to the Tioga Gate. Although they have reached the gate, there is still quite a bit of work to be done. The road needs to be widened and repaired. There are still five active avalanche zones, Dana Meadow, Marmot Dome, Olmsted, Spring Hill, and Yosemite Creek. We are hoping to be able to allow admin traffic to the meadows by Monday or Tuesday. All personnel that will need to go up on Tioga road will need to have been avalanche trained and certified. We hope to have White Wolf road plowed by late Saturday. There is no projection as to when the road might open. All is dependent on the Avalance zones. I will keep you all posted as things develop. (J. Cyr - 6/01/06)

6/6/2006
雪崩トレーニングを受けたパークスタッフは、今日からTioga Roadに入れるようです。
Tioga Road will be open today to Administrative Employees who have completed the avalanche training only. (R. Soden - 6/6/06)
