Big fire in the mountains above Tucson

9:25 pm

At sunset tonight I went out into my back patio to enjoy the evening air and noticed smoke trailing off from the mountains on the opposite side of the valley. Taking a closer look with binoculars I discovered a major forest fire blazing on the front range of the Santa Catalina mountains, about a thousand feet above the city.

To give the layout, our home is on the west side of town, on a hill that overlooks the city. The Santa Catalina Mountains border the north side of Tucson, about ten miles away. (Below the fold is a short video showing the mountains and the smoke, taken today from the west side on one of the overpasses above the interstate, slightly south of my home. The video shows a view similar to what I can see.)

The fire, dubbed the Finger Rock fire after the canyon in which it started, was originally ignited by lightning last week, smoldered for a week, then re-ignited today and is spreading fast. While Diane and I watched this evening we saw the flames leap across from Pontatoc Ridge to the opposite wall of the adjacent valley, Ventana Canyon, which Diane and I last hiked in 2013. I saw flames that were easily 100 feet high.

We have hiked on Pontatoc Ridge. That trail is certainly badly damaged or destroyed. The lowest parts of the fire now appear to be burning at about 500 feet above the nearest homes in the foothills below. When it jumped into Ventana Canyon it appears to move uphill, so at the moment no one’s home is threatened. This is a very very rugged area. It will be difficult for fire crews to get there, no less work to control the blaze.

As the evening progressed and darkness set in the extent of the fire became easier to see, as the flames now stood out in the darkness through the smoke. Though the Forest Service seems sanguine about it, this is not a trivial fire. It threatens the entire front range of the Santa Catalinas, which is one of Tucson’s major recreation areas. Worse, it is close enough to the city that it poses a threat to the homes in the foothills.

Stay tuned for updates.

The first suspension bridge connecting mountain peaks

2:25 pm

Switzerland is about to open the first suspension bridge ever built between two mountain peaks.

The bridge, suspended 9,700ft in the air, will also have a partial glass floor to allow visitors a once in a lifetime view of the 6,500ft drop between the Glacier 3000 and Scex Rouge.

It is scheduled to open in November, and is being built in an effort to attract more tourists to the Swiss Alps.

Out of the Canyon

6:18 pm

We exited the Grand Canyon on schedule at about 1:30 on Thursday. The hike out this year took one hour longer than last year, mostly because we took longer breaks.

As always, the Canyon is a sublime place, hard to describe to those who have never been there and unnecessary to describe for those who have. We hiked in, did an 11 mile hike the one day we were at the bottom, then hiked out today.

Posting will resume but will remain light until I return home on Sunday night.

More fraud in peer-reviewed science

9:36 am

The science journal Nature today announced the retraction of two controversial stem cell papers.

The two papers reporting the stimulus-triggered acquisition of pluripotency (STAP) phenomenon appeared online on 29 January. Questions about the papers arose almost immediately, leading to an investigation by RIKEN, the headquarters of the network of the nationally funded laboratories that is based in Wako near Tokyo. Investigators documented several instances of fabrication and falsification in the papers and concluded that some of these constituted research misconduct on the part of [Haruko] Obokata [the lead author].

Japanese media recently reported that authors had agreed to retract the papers but were discussing the wording of the notice. In the note that appeared today, the authors point to errors previously identified by RIKEN investigations in supplementary documents. They also identify additional errors in both papers, including mix-ups in images, mislabeling, faulty descriptions, and “inexplicable discrepancies in genetic background and transgene insertion sites between the donor mice and the reported” STAP cells. [emphasis mine]

The list of errors now documented sound astonishing. In fact, I can’t see how any serious review by any competent specialist in this field could have missed them all, which suggests that for this research at least the peer-review process is mostly a sham. In fact, in the article Nature admits that its

On the road

6:00 am

Posting for the two weeks shall sometimes be limited to the evening hours, as Diane and I are heading east for the first time in two years to visit the Smoky Mountains on the border of Tennessee and North Carolina.

We decided to drive, partly because it is cheaper, and partly to avoid the TSA (Airlines: Pay attention!). It also will give us a vehicle for driving north after our hiking vacation to visit friends and family in Maryland and Pennsylvania.

I intend to post about our trip. I should also do most of my appearances on the John Batchelor Show as well. The only negative is that I will be out in the real world when both Falcon 9 and Cygnus finally complete their next flights. I will only be able to post about it after the fact.

Doing the Grand Canyon Right

2:50 pm

The Tonto Plateau

The one thing about the Grand Canyon that attracts hikers is its intimidating nature. People feel challenged by its large size and depth, and want to prove to themselves that they can do it.

The irony of this to me is that it is that intimidating nature that generally causes most people the most problems. People worry about the climb out. They worry about the heat. They worry about the lack of water. And they worry about vastness around them.

All of these things — the climb, the heat, the lack of water, and the vastness — must be dealt with. Each has caused the death of many visitors. Each could kill you if you are not prepared. In fact, one or all of these factors are probably the primary causes behind all of the approximately 300 rescues that occur each year at the Grand Canyon.

Yet, none of these factors is actually the biggest obstacle for most people trying to climb in and out of the Canyon. Instead, it is the worry about these things that causes people the most difficulties.

At the rim 2

3:42 pm

We have returned from inside the Grand Canyon. We hiked out on Tuesday, doing the climb up in what is for us record time, arriving at the rim at 12:30 pm after 7 hours of hiking. We were down at Phantom Ranch for two full days and three nights, doing some really spectacular day hikes each day. I will post some further details, with pictures, once I get home.

We are still touring about here in northern Arizona and will be until Sunday. Right now I am sitting in the patio of the motel at Grand Canyon Caverns, about two hours west of the national park. This morning we drove down to the Colorado on the Hualapai Reservation, using the only road on the south rim that reaches the river. This weekend I will be participating in a long term cave dig project here at this somewhat famous commercial cave. The dig has been going on for years in cooperation with the cave’s owners. This will be the first time that I will contribute to the project.

At the rim

8:02 pm

The Grand Canyon from our motel room

After a 5.5 hour drive we arrived at the south rim of the Grand Canyon and checked into our hotel. You can see the view from the window on the right. Not very spectacular, but then, you don’t spend much time in a hotel room on trips like this.

Tomorrow we take the shuttle bus to the North Rim, where will spend another night in the lodge there. On Saturday, we hike down on North Bright Angel trail, and will stay in a cabin at Phantom Ranch for the next three nights, doing day hikes from the bottom of the canyon on Sunday and Monday. We will hike then up on Tuesday, coming up Bright Angel trail to the south rim, completing our first rim to rim hike. Once we check out of our hotel tomorrow, we will be out of contact with the internet until we return to the south rim. I hope the world doesn’t fall apart in the interim.

This will be Diane’s third trip to the bottom, and my fifth. I can’t express how happy I am to be back. This is truly one of the grandest spots on Earth.
