On the flip side, the sonic boom witnesses described it as ‘faint’.  So on Thursday, we decided to withdraw from the field to go back to Austin and try to sort out facts with models. Something does not compute and we want to know why.   I predict based on the shallow angle and lessons learned in Wisconsin by fellow hunters, that the strewnfield will be very long and very low density. Perhaps 15 hours of walking per fragment found.  At this point, it will be the public that finds the fragments.  I also believe that the trajectory solution should be shifted over 50-100 km east.

We then found a couple with a few hundred acres who let us search there property, he also had a vineyard and was kind enough to offer up several bottles of wine as a expedition sponsor of sorts. (Score!)

He also secured for us 1,000 acres of his neighbor’s land who had seen me on Channel 7 news in Tyler. The predicted strewnfield should traverse this property. The ground is flat and eaten down by cattle. Wonderful terrain for hunting.

Discussing the Doppler data with David Gonzales, we postulated that the meteorite event occurred between sweeps and the material was on the ground when the current image was taken. Our theory is that the return is off the dust and that it is blown south for several seconds when imaged.  That throws the strewnfield northerly.

We saw a wild boar that had been captured. It wanted to bite my foot. These critters are quite smart and considered land sharks as they eat flesh and also bone.

This was Stephen’s last day in the expedition. Our gracious patron invited us into his home and offered him some homemade wine from his vineyard and a chance to trade tales from our long and colorful past. The evening was quite a blast and not for mixed company.

So far we’ve not run into the fabled black panther, aka a dark mountain lion. But is is known to visit this property and the landowner lost all his chickens to it during the winter. I did see likely lion tracks in the mud down by the swamp. As to the Z problem, we had our first sightings tonight deep in the swamp so we think we are closing in on the strewnfield. Stay posted!

If anyone has found a meteorite fragment, please call me in the field at 512 773 7811.  Fragments should be midnight black with a white/grey interior and a magnet should stick to them.

Meteoritic or Volcanic

The original submition is practical. They don’t know if it is volcanic or meteoritic and are submitting it to a scientific journal, not a sensationalist approach using a media outlet. So the original authors are sincere, on a first evaluation. No religious agenda is apparent, so this needs further study.

“Mount Ararat is an ancient, isolated volcano in eastern Turkey near the borders with Iran and Armenia. According to the Bible, the mountain is the final resting place of Noah’s Ark. Many an expedition has tried and failed to find the Ark’s remains.

The northern and western slopes of the mountain are closed to public so how two physicists gained access is anybody’s guess. However, today Vahe Gurzadyan from the Yerevan Physics Institute in Armenia and Sverre Aarseth from the University of Cambridge in the UK, publish an account of a remarkable discovery they made while walking in the region.

At an altitude of 2100 metre, at coordinates 39˚ 47′ 30”N, 44˚ 14′ 40”E, they found a well-preserved and previously unrecorded crater some 70 metres across. (Google Earth is of little use. The resolution of the imagery at this location is poor.) That’s a decent size for a crater that has gone unnoticed for so long (although new craters of this kind of size do turn up from time to time.)

The question of course is how this crater was formed. One possibility is that the crater is volcanic. But Gurzadyan and Aarseth raise another: that it is the result of a meteorite impact. They rule out a glacial origin on the grounds that 2100 metres is well below the glacier line.

Gurzadyan and Aarseth publish their account with the intention of attracting interest so that the crater can be properly classified.

New craters are important because they help determine how heavily the Earth has been bombarded in the past. And while small craters are far more numerous than big ones on other bodies in the Solar System, the opposite is true on Earth because small ones tend to be eroded away more quickly.

Interestingly, the crater wasn’t their only discovery during their trip. Because the region is closed, it is virtually unexplored. Gurzadyan and Aarseth say they also stumbled across the remains of a 5th or 6th century Armenian basilica that is unknown to experts.

Sounds like an adventure in the making for anybody with the time and inclination to go. (And with the necessary permits, of course.)

I’ve updated Expeditions and added a paper on how meteorites are found. It brings to light how to go about finding your own meteorite.

Overdue by over a year, TML now has a flexible website that will accommodate our plans for an extensive meteorite identification video course.
