Anyone getting the idea to follow the Yellowstone River from the south, up to where it intersects with the Missouri, (a great scenic flight BTW) be advised there is one particular set of smaller wires about 40' above the river (but big enough), in an area that is far from any development/in the middle of nowhere, with the poles hidden by trees. We all look for the poles right? They are a pretty good indicator of wires are after all, but when the poles are obscured a bit it can up the ante quite a bit. Balls on the wire...ha! Nope, in this case ( I went around twice for another look) just the wires themselves were the indicator that you might have a real problem if you don't pull up real soon.
Making up somewhat for this bit of excitement was the big sand bar where the rivers tied in, custom made for a fat tired plane to land on and obverse the current flow.
Anyone following the Snake downstream out of Alpine WY, over and down from the dam about 8 miles, there are a large set of lines about 300' above the river. Their unusual height, though on not so tall towers, is because the river cuts so deep there and the towers are up on the bluffs. The few balls have faded and shifted their position, well off to the side. This situation is a perfect storm for the unwary pilot:a scenic and somewhat heavily flown route, and no notice on the SLC sectional. Someone, me I guess, needs to lobby the Feds to get a call out on the chart for them, a heads up. They've been on my radar for over 20 years, and I'd feel terrible to hear about an accident due to them. 43.488811° -111.428655° if anyone is interested, and yes the river has a lot of great gravel bars!
I HAVE been preemptive in personally taking down 2 abandoned MET towers, unlit, galvanized grey/no paint or lights, and 150' high! New regs on these things make these older ones technically illegal, or at least out of compliance. Hard as hell to see, and cable braced, cut a few cables with a battery operated cutoff wheel and they come down real easy, kinda fun too. The companies that put them up, after the wind farm idea falls thru, don't take them down! They are not worth the labor involved. It's up to us (no one else cares, maybe birds) to contact the landowners and get it done. They are always in quite remote areas, and have no ready vehicle access, if a road was cut in for it's erection it is long grown over. As a result, the light gauge tubing and cabling are left on site, though I did pack out a few hundred feet of the cable for misc. use, that was my pay.
