The old telegraph or telephone poles are no longer in use but their tripod shape is interesting. It's too difficult to pound a telephone pole into the frozen tundra so the trPpod almost floats on top. The three legs of the tripd can all pivot so as the tundra's surface thaws, freezes, and shifts the lines remain intact. The tripods are a constant â„¢nmpanion all through the tundra. |
