Oh, for Heaven's Sakes, people!
1. a British Columbian
2. One who worked as a welder's helper on 30" pipeline, for a short time in the 70's
3. One who spent most of 1979 flying all over BC, on assignment by my employer.
4. Worked for the largest Oil Company in the country for 27 years, the last 13 years at a Distribution facility, supplied by Pipeline from Edmonton.
I can POSITIVELY tell you it is one of several very common sights
out West, and probably in Quebec and so on as well:
1. Right-of-way for high-tension Hydro-electric cross-provincial lines.*
2. Right-of-way for underground oil or natural gas lines.*
3. The Canada/USA border, as suggested earlier.
*All of which require substantial cut-back, both for access during construction, access for maintenance and emergencies, and aerial monitoring (they have airborne electronic instruments that can check for problems and weaknesses in the pipeline, even underground).
I have seen all kinds
of these, flying around BC. And YES, they go in straight lines for MILES, regardless of all but the worst of terrain. I remember carrying the ground-cable for a boom-welder on a big cat, and its radiator was sometimes 15 feet behind me -
and ten feet ABOVE!
In fact, if you look closely near the left edge of the pic, you can see two instances of shadows
on the down-hill slope in the "slash-trail", as they are called.
Believe me - you can take this to the bank!
