The hair stood up on the back of my neck yesterday
Am currently surveying in outback frontier town of Coober Pedy . Suggest if you have a couple of minutes you google earth and zoom in ! Looks like a lunar moonscape. ’tis an opal mining area of world renown.
Any rate I was surveying a dug out parcel of two acres in some break away country where am dividing the allotment into two parcels. The client wanted a new boundary to miss an airshaft, preferably straight between A and B. There are mounds of rubble, rock piles and rock in soils and you could not see along the line due to the undulating terrain.
Well I placed a peg to miss an air shaft and told land owner to walk down to near top of cut and place another peg. I then located the two pegs by radiation as visible from side view. Then computed a point on extension of the two placed pegs and placed that peg.
Imagine my surprise when I dropped the survey in Liscad , carried out my calculations to determine boundary corners and then notice three internal pegs were all on a straight line and their production intersecting the corner!
The hair stood up on the back of my neck!
Even more when the computed end point which was not visible at the base of the excavation from using the two pegs placed was exactly where the client wanted it .

RADU,
When that happens, you’re supposed to do a little dance in a circle, all the while saying “I’m Good, I’m Good”.
Then, have a beer for a job well done. :beer: :beer:

That’s even more rare than setting two temporary markers at random and discovering the bearing between them is due east or north based on your current basis of bearings.

You have just now “screwed” every surveyor that man will ever hire, or the ones his blokes will hire because you are so good… He’ll say “you just poke the pegs in the ground anywhere you want and they are in a straight line and the surveyor is done… cheap as dingo droppings…”
(the foregoing was all in jest, of course)
But, I must say Richard… Isn’t this place a bit far from home (Adelaide?)? Is there not another surveyor within close proximity (or withing 3 hours) to there? I googled the directions and it’s about 10 hours by driving. Or did you fly out there? In 10 hours I can be almost anywhere in the east of the Mississippi River in the U.S.A.
I hope you got windshield time in either case.

Within 300 ks radius there are kangaroos and with in that area
it is humming with exploration , with many different mines set to go into production. They have there own in house surveyors.I am up in the town ship and environs doing boundary surveying.
This trip drove up as a longer trip 850 ks from Adelaide . 1 day to drive. flying is 2 hours $400 each way. Problem is to have all gear with me plus materials, must send before and pick up after from freight depot then transfer to hire 4wd vehicle.
last time I had damaged equipment !
Also have jobs to complete on way back 250k from Adelaide.
So just as easy to drive… Just put mind into neutral… ‘ on the road again…….”
Currently sitting in underground motel room . will post pics later.
Walls are carved into ground and exposed. This place is an old converted opal mine. The owners found 100 plus million year old opalised sea shells ( 100m above sea level now)when boring out additional rooms.
Incredible I am sitting shirtless as I type and it is winter time. During summer here when 40 plus C outside you need a sweater on to stop “freezing”
Miss Heidi actually surveyed yesterday as she has finally learnt OZ surveying lingo…

Wow, it is amazing how that stuff happens every once in a while. I once rotated a deed plot randomly to get it closer to the correct bearing system, and once we tied it in to NAD ’83 I was only 30 seconds off.
I have some Coober Pedy opals, being my birthstone I am partial to them.

Have a good trip, it looks like it is a busy one for you.

OMG! What kind of obsolete equipment are you useing down there? I hope you’ve at least got on a lead vest!

No problem Mate!! Aussie surveyors are TOUGH!! Besides, all that radiation makes their “tesatimonials” glow in the dark so they are able to continue the survey well after sun down. 😉
