These shots was taken from my living room while watch on TV the parade of tall ships enter Boston Harbor On June 17.

I really like the power lines. Composition! >Alan

Here's a B&W conversion of a sailboat on SF Bay with the Transamerica pyramid in the background and one of sailboats and the Bay Bridge with 10 triangles

Dane004, wonderful picture of the Wyoming Coal Power transmission lines.
I suspect that this is of the three parallel lines running from the Jim Bridger power plant near Superior, WY, then westerly to the southern Idaho area before they split off into single lines. I was the lead surveyor for the route survey to establish the alignment for those lines in the early ‘70s. Our portion of the project ran from Superior to the Idaho border. Later on we did other portions of the route across southern Idaho and southern Oregon into Medford, Oregon.
During the surveying I remember seeing ruts in the desert, somewhere north of Rock Springs, from the Oregon Trail wagon trains of the 1850’s. From a surveyor's point of view, it was interesting, at least one portion of the line ran 28 miles between angle points with minimal geodetic control markers (pre computer and GPS era), hot & windy in the summer and bitter cold in the winters.
We did the surveys for these three parallel lines over several years. The towers were unusual, having a center pivot point ball that sets in a socket on the ground and guy wires to the ground to support the tower. Survey crews would figure out the length of each of the guy wires depending on the terrain along each proposed guy wire.
The towers were assembled in several yards near highways or railroads, then, when enough were pre-built, a big, really big helicopter would come in for a few days, latch onto a tower, cut to length guy wires and all, with a cable and fly it to its location, hover over the center point while ground crews set the ball into the socket and attached the guy wires to their previously set anchor points. I don’t remember if the helicopter or a ground crewman released the cable from the tower.
A couple of perhaps interesting tidbits from my feeble memory, during construction of the third line a dozer operator ripped out a guy wire on the second line and towers fell like match sticks, 5 or 6 if memory serves. Normal inline towers had 4 guy wires while some angle point towers had up to 16 or 32 depending on the stresses the tower had because of the horizontal deflection angle or even the vertical rise or fall to the next tower.
