I was part of a University Seismic team in a summer of '61 that had a license to use a pallet load of C4 in an lake flooded old mine shaft near Flin Flon, Manitscoldhere (MB) , an old gold mining town I once lived in as a wee tadpole picking up RCMP radio signals on our TV since there was no TV signals in 1961. But I was 9 and knew how to tune in the sideband being close to the broadcast, when I got bored staring at random dots on the screen, trying desperately to find a pattern, until it came, I heard, I saw. or was it verdi vici veni.
What fish inhabited one of these 100k+ lakes in Manitoba rose from the dead shortly after the surface rose 6".
Meanwhile I was stopping all traffic 250 miles North between two small mining towns. Except there was none.
Just before daily blastoff time, a mining bus came full speed towards me standing in the middle of the pavement, only to play chicken with me wearing a stupid looking white hardhat and big Red Stop sign.
As you all know by now, that driver did stop!. And I lived to tell about this recording incident. After he blurted out what the .. was I doing here, I calmly said, we're just blasting ahead.
Do you mind waiting?
Oh of course not.
Not a peep was heard nor a shake except for the feet of a walking deer and running brook a 100 yds away from the nearest geophone that pegged the needle. I could even peg the needle if it was on the pavement and I did knee flexes on the other side. But the boys in the truck doing galvo and mag recording duty today captured all 16 channels in succession and later uploaded tapes analyzed by seismology students found Uranium deposits from the reflections as deep as 30 Miles x 250 miles long for about 5 minutes and maybe a few deer hooves.
Then, I motioned the bus driver to pass, as he scratched his head and I looked as if everything went ok.
A lot of floating fish in that pond after recording every day for a week. But my favorite recording near Kenora , Ontario ( in between fishing) when we took for cover after dropping a dozen sticks of geo-gel (by our licensed boss) was a massive tree trunk that came out of the mineshaft with some water and went clear past us overhead.
Johnny Unitus said. go long and it did.
But this is the first time I've heard of a fishing gadget that uses lots of Joules for fishing. I always though it was better to fish for jewels like Sharks decorated with all sorts of jewelery and hooks 2 hrs past the San Franciso Bridge. I least that's what I did once. A long day but the Yellowtail and Cod was worth it.
