Mystery of Death Valley’s Sliding Rocks Solved

Hundreds of mysterious engraved trails have been stumbled upon at the Racetrack Playa of Death Valley in California. There’s almost always a rock sitting at the end of the track, but no one has actually seen a rock — not a pebble nor a boulder — sliding on this nearly flat, dry mud surface. What gives? Several decades of speculation range from powerful winds and ice flotation to dust devils and slick films.

Now, for the first time ever, researchers have observed the sliding rocks in action. Finally! Under just the right conditions, thin sheets of ice blown by light winds push the rocks across the dry lake. The work, which turned out not to be “the most boring experiment ever,” was published in PLoS ONE this week.

Militarized Schooling? “Newtown Was A Nuclear Bomb That Changed Everything”

Returning students at Hillsborough County Public Schools in Tampa, Fla. found 20 new armed officers in the elementary schools in the first year of a plan costing about $1 million.

The school board also approved security training for employees, the hiring of a safety consultant and more measures to control school access, such as fencing and buzzers.

Meanwhile, all 16 schools in the Coeur d’Alene, Idaho, public school district have been enclosed in security fencing and each school limits visitors to a single entry point, officials said. This September, for the first time, two police officers will patrol elementary schools, at a cost of roughly $68,000 from the district’s state funding.

…officials continue to allow four anonymous employees to carry firearms on school property. Bulletproof glass and panic buttons have been installed, and officials held schoolwide assemblies for security training.

Because, clearly, the solution to “too many weapons in society” is “more weapons!”

  1. In cold war terms, this was known as “Mutually Assured Destruction”, or more simply, just plain MAD… :rolleyes:

  2. Changed “everything”? Hardly – especially no change in any real control of access to weapons.

  3. I’d say it was incremental not a massive change. Everyone thinks Hell is over a cliff but you can get there on a broad, easy road, according to the old preachers…
