More archaeology porn

Nothing much has been happening the past couple of days, so here are some pictures I took in at Canyon de Chelly last Christmas (as always, click to embiggen):

This rock art panel was obviously painted after the Spanish arrived in the area. According to our guide, it depicts the military expedition of Antonio de Narbona in 1805, in which a large number of Navajos were killed or taken captive.

 

This should be immediately recognizable to any Southwestern archaeology geeks reading my blog. For the rest of you, it’s a picture of the well known White House Ruin, probably the most visually impressive ruin in Canyon de Chelly. It was built by a people known today as Anasazi or Ancestral Pueblo.

 

This is White House Ruin again, this time seen from the canyon rim. Construction of this pueblo began around AD 1050, and it seems to have been occupied for roughly 200 years. Why they left is still very much an open question in archaeology, although many of the current theories tie abandonment of this and other pueblos to changes in climate.

Time for plan B

From an old episode of Stargate SG-1:

Col. O’Neill: It’s time for Plan B.

Maj. Carter: We have a Plan B?

Col. O’Neill: No, but it’s time for one.

Today the Russians have grounded their entire fleet of Soyuz spacecraft after one of them was destroyed in a crash. This is, of course, the vehicle that NASA is relying on to resupply the ISS since the last shuttle has retired. Currently, there is no backup. The crew of the ISS is stranded in orbit until either the Russians fix the problems with the Soyuz or SpaceX begins commercial flights to orbit.

As I’ve said before, the replacement for the shuttle should have been in service 20 years ago.

Making up the law as they go

Apparently that’s what the Long Beach (California) PD is doing, according to this story. Taking pictures of something that a police officer doesn’t find pretty (“with no apparent esthetic value”) is considered suspicious behavior, sufficient to justify detaining the photographer. I’m not an attorney, but it sounds like what they’re doing is a Terry stop. This is less burdensome that being arrested, certainly, but it is still an intrusion that needs to be carefully controlled. Not only is it offensive for a law abiding person to be detained without good cause, but needless investigation of innocent people takes police time away from other, more useful activities.

Since the department acknowledges that police officers are given no training in what qualifies as “esthetic,” we must assume it’s based on the personal preferences of each officer. It’s difficult to imagine how such a standard could possibly be defended in court. Even more so when the list of “suspicious” behaviors also includes looking through binoculars, taking notes, and inquiring about an establishment’s hours of operation. (Will business owners now be told not to post the hours they are open, lest that information somehow be used by terrorists? That would seem to be as reasonable as anything else in this policy.)

Giving a whole new meaning to “little green men”

By an interesting coincidence, while I’m here enjoying WorldCon, the UK Guardian decided to run a story about the possible outcomes of contact with extraterrestrials. The money quote is this: “‘Green’ aliens might object to the environmental damage humans have caused on Earth and wipe us out to save the planet.”

While I agree this is theoretically possible, there is no reason to consider this any more likely than aliens attacking because they object to our over protection (as they see it) of our natural environment. It’s absurd even to speculate about what might provoke hostility from a member of another human culture without knowing anything at all about that culture. It even more absurd to speculate about what might provoke an unknown extraterrestrial culture. Anything we can imagine, and probably a great many things we can’t, might be the trigger.

Seriously, is it so hard to think up legitimate reasons to protect the environment that people have to come up with silly ones?

And now for something completely different

Nothing about archaeology or trains today. I’m spending the next few days at the World Science Fiction Convention with my wife, sister-in-law, and nephew. In that spirit, I offer a link to this wonderful review of David Weber’s Honor Harrington series of books. I have read only a few HH stories, but I find that I wholeheartedly agree with everything said here.

BATFE firearms trafficking: What could possibly go wrong?

Well, apart from this, that is. Including the Brian Terry murder, at least twelve violent crimes in the United States have been linked to guns that the BATFE knowingly allowed to go to criminals. The number of crimes in Mexico connected to this program is unknown, but almost certainly a lot higher. And there’s no telling how many innocent people will be robbed, raped, or murdered with guns that were allowed to “walk” before they are all finally recovered.

This is way past being a regrettable mistake. High ranking people in the BATFE and the Justice Department absolutely need to go to prison for this.

Sierra Ry. train porn

Here’s a few pictures I took out behind the roundhouse at Railtown 1897 State Historic Park.  (click to embiggen)

 

An old Shay is awaiting restoration. This type of locomotive uses gears instead of rods to drive the wheels. Speed was low, but pulling power was much higher than conventional steam locomotives.

 

Here’s the other side of the same locomotive. This angle is not as interesting visually, and very few historic photographs of Shays  show this side.

Underneath an awning they’ve got an old narrow gauge boxcar saved from the Yosemite Short Line. Sadly, there are no plans at present to restore this historic little gem. I’d really hate to see this car just rot away.

 

Most of the equipment at Railtown appears to be in need of a little work (some more than others), but #3 is fully restored and running. It takes passengers on a short but enjoyable ride through some beautiful foothill country.

There has been some concern that Railtown might have to close because of state budget cuts. I urge anybody who likes old trains to get out there and ride this one and help them continue to operate.

Ridin’ the train, part 2

Spent the day in Jamestown, CA town. Among other things, we paid a visit to Railtown 1897 State Historic Park and took a ride behind Sierra Railway #3. I’ve got some good pictures, but it’s late and I’m tired so I’ll post them tomorrow.

Electronics FAIL

A while back I blogged about a new Navy ship that dissolves in salt water. Did the same engineering team design the radios used by federal agents? A newly released report indicates that it’s very easy to monitor both the conversations and the location of anyone using this kind of radio. Not only that, they can also be jammed by a $30 child’s toy.

How the hell does this kind of crap get selected for government use? The people involved in making the decisions have to be corrupt, stupid, or both.

Archaeology is fun

Especially when you combine it with computer games. A team at UCSD are experimenting with using a hacked Kinect to rapidly create 3D scans of archaeological sites. This technology can’t come fast enough for me, and I think anybody who has ever painstakingly mapped a cluster of rocks with pencil and clipboard, on the off chance that they might be significant*, would agree.

*It’s amazing how often what appears on the surface to be a deliberate stone ring will prove, upon excavation, to be just a random bunch of rocks. Sometimes the human brain is a little too good at seeing patterns.
