Haven't taken the time to build a power supply to spin up the gyro, but did get a chance to disassemble Jethro a bit more. Here is what was found in the cylinder above the gyro compartment... The bottom cap contained a water detector (left) and a level sensor (right). Here is our...

You're asking if we have considered hauling a large rig from the nearest large city (Fairbanks, 4hrs drive by car), up a mountain, over tundra, to yank a 300ft long, 12" ID welded steel casing, and then somehow reinserting and sealing it. Ahh, no.

I was at an old White Alice site on Friday. Unfortunately, everything had been razed. Also, spotted your M1010 brother in Delta Junction, AK. Will try for a picture and story next time I pass through there. And I think I'll retire at the end of this year. Can I go look for stuff with you...

Have you checked the night stand? I'm sure your meds are there. ;)

I hope to spin up this gyro before EoM. The rear connector has been removed and a pigtail added to make it fit this application, so I can't just get the units original pinout and hook her up. I may just have to break the seal on this one to figure it out, but then I'll be able to run Jed and...

Ahh, sorry about that. Thought I'd spelled it out earlier, but I see that I haven't. University of Alaska-Fairbanks (UAF).

Hmm, what's that little steel can in the bottom of the last picture? It can be accessed from a hatch on the side of the instrument. It actually looks like a hatch you'd see on the side of a bomb in one of those spy-type terrorists-have-the-bomb movies. Do I need a plastic screwdriver and should...

They set up a hydraulic press system on top of the well casing, lowered the tool, gave it a twist to lock onto the sensors upper holelock dogs, and began pushing (pulling). At first, nothing. Just as the system registered 20Tons of upward force, there was a TWANG!. The pressure dropped to under...

Last year UAF attempted to extract Jethro without my help, although I was on site to witness the attempt. They preferred a brute force method over my finessing. They failed. In fact, they broke the recovery hook. Jethro remained hung up on a weld seam about 14ft down. After the winter to think...

Another item found on site. A manual holder?

An old USAF test site. Some documentation I have found on the project says it was funded in 1966 by the Air Force Office of Scientific Research (AFOSR) and the Advance Research Projects Agency (ARPA). The site is now owned by UAF whom I am working with to reoccupy several of these sites. What...

Also found on site... I suspect it is one of two handles for unrolling a spiral-4 reel, but not sure.

Negative. Bright flash and a severe sun burn followed by a loud bang. Something like this... http://www.youtube.com/watch?v=l7qOxicZde0

THAT would have been even cooler to have found an unused, virgin 62yr old, GI battery! But, based on the white crud around the filler cap threads, I'd say it was been filled and used.

...or a mini sub. :deadhorse:

About .6V per cell and 3.2V total. Cells are dry.

I had tried to date this battery without much luck, but now that I've posted a picture, I see the 1952 stamped on one of the cell terminals. :doh:

I found a few more goodies on site. Here is one. 'The Electric Storage Battery Co' made batteries for submarines and eventually became Exide. With all of the do-dads sticking out of this battery case, I can imagine it in a large bank of batteries for something like that. I have not been able to...

Negative. Worldwide. There will be more pictures of this unit and the others, as well as any info I can dig up of this particular project. Questions are ok, but I am somewhat surprised that there is so much interest since most here are focused on wheeled OD.

Seismic sensors of this type are placed as far from buildings and 'civilization' as possible to minimize cultural noise that might obscure teleseismic signals. And when they are spread out over a large area to form an array, they can better triangulate on the signal sources.
