On June 1st, we will be preparing to cut through the Olmsted Avalanche zone. June 2nd, we intend to cut through the zone at Olmsted. Starting early, when there is a good freeze is imperative. Once we have cut through, the crews will go back west and let the snow takes its course. No work will be done for the rest of the day. An assessment will be done on Friday morning to see if it is safe for the crews to go through and proceed east.
Tioga Road report for June 2
Park crews were able to cut through the Olmsted avalanche zone today. After the cut, all personnel were sent back to work west of the zone while the avalanche team checks out the zone and waits the normal 24 hours to see if there will be any movement. If there is no activity, the crews will proceed eastward tomorrow.
Tioga Road report for June 4
Today, the crews were able to plow through avalanche zone 21 (Marmot Dome) and meet up with where the County left off. This does not mean that the road is opened. From Olmsted Point to Tuolumne Meadows, the road is plowed only a bit wider than one lane. Equipment failures have lead to this. We still need to widen these approximately 10 miles of road. We still have three active avalanche zones. In these areas, the road will remain only one lane wide until the zones are downgraded. The avalanche team believes Olmsted zone will probably remain a n avalanche zone for at least two more weeks. The road crews still need to plow out the administrative areas, widen the roadway, do ditching, road repairs, sweeping, and most of the signs along the road will need to be replaced. We still do not have a set opening date. We will be opening Segment 2, from Walker Party to Yosemite Creek, Thursday, June 9th.
Tioga Road report for June 14
Avalanche zones are still active on the Tioga Road. Park staff traveling on the road for administrative purposes are required to have avalanche training and equipment.
On June 14, crews began to remove boulders from this rockslide near Olmsted Point.
