Tioga Corridor

NPS opens the Tioga Pass Road on 1 July. Our big snow year made clearing snow, avalanche zones and downed trees more laborious than usual. Because water and wastewater systems in Tuolumne Meadows both have problems, it's not easy to have park staff living up there yet. These important people are needed to staff the entrance gate, patrol the road, provide information to visitors, oversee Wilderness access and permitting with backpackers, patrol trails, manage a huge campground, clean public restrooms, set up seasonal housing and make sure that all utility systems are functioning well. It's been our disappointing experience that when the Tuolumne Meadows area isn't staffed by NPS, some visitors can be more destructive to the high country's values.

The partial opening of Tioga during the past week, with one-hour morning and afternoon windows is something new. While cars can't stop on the transit (except to drop-off or pick-up backpackers with permits), the windows have been heavily used by visitors and locals moving between eastern and western California.

NPS has generously allowed bicycles to ride Tioga during all daylight hours. This is one of the best bike rides on earth and is a terrific national park experience. Birds, running water, and the purr of bike tires - so nice!

Of course, as mentioned elsewhere, Tioga is open all year - just not to vehicles. Plenty of people travel this corridor all through the winter months. Those contemplating hikes in the next few weeks should expect lingering snow, difficult creek crossings, and wet, muddy trails. We hope that visitors will be gentle on the landscape as it dries out.

More and more Spring


The excellent Dave Wyman took this unearthly photo of a favored place on Earth. His autumn YA photography course has filled, but there are plenty of other great ones, including Howard Weamer's August high country course. People on our September China national parks trip may well come home with images that compare to this.
A road crew friend told me he didn't think Tioga Road would be open for Memorial Day; avalanches are still a factor. Half Dome cables should get installed next week, in time for those who have permits for Memorial Day weekend. Mariposa Grove Road opens this Friday to all vehicles.
Senecio is in bloom along Southside Drive. Mallard and merganser ducklings have been seen in calm Valley waters this week. A lazuli bunting was singing atop a still-leafing-out black oak near Cook's Meadow earlier today. Birders on this morning's walk also got to compare Vaux's swift with violet-green swallow flight.
Bit of rain overnight. The river is coming up a bit, a little over average flow again, with Table Rock fully covered. Side streams are still increasing; water leaks on to the road near Fern Spring now and Sentinel Creek is the biggest it's been this season.

Head for the Hill's Studio


The Wawona Visitor Center is opening today for the summer. It's in the Hill's Studio next to the Wawona Hotel. If you haven't been in there since the new layout and exhibits were unveiled last spring, you really should make a stop on the way through Wawona. We were excited to have a huge Thomas Hill Yosemite painting prominently employed during the last presidential inauguration.
The road from Lee Vining is open to Tioga Pass, and plows have chewed down into Tuolumne Meadows from the east side. On the west, our guys have gotten the plows to Olmsted Point, where a very sensitive avalanche zone is found.
Blue skies with a healthy upcanyon breeze this morning. Western Wood Peewees are wheezing in the Valley. Dogwoods still coming along.

Mist Trail Open



The Mist Trail to the top of Vernal Fall opens today. Lots of people have been ignoring the closed gate for the past week, but the considerable ice build-up during last week's cold shows why NPS didn't open it until now. More freezing could prompt a closure. The "Ice Cut" from Clark Point to the top of Nevada Fall is still closed.
Road crews have plowed all the way to Glacier Point, but still have a lot of clearing to do, to get two lanes fully open, and all the parking areas cleared of snow. The Tioga crew has pushed up to near the May Lake turn-off, still with 7-9 feet of snow.
May 1 snow surveys show the Tuolumne watershed with 141% and the Merced watershed with 134% of average water content in the snowpack. The Merced River almost hit 3000 cfs at Pohono Bridge last night and warmth for the next few days means our river will be getting to the exciting level.
