Here's a nice olive green WT CD 107 that is on an old telephone line that stretched between the Lower Meadow road and Marcy Dam in the High Peaks region of the Adirondack mountains. There's a small 4x4 road that travels 2.8 or so miles to the dam and these simple 2-4 sidepin poles followed most of the way. Only a few had glass or remnants of it, this was one of them. A couple others held clear CD 115s, not sure what brand.

This pole is leaning over the road and very loose in the ground, so it's my prediction that the park rangers will remove it as soon as they are aware.
