Mt Whitney Zone Forums General Discussion are the cables left up year round?

If you are talking about the Mt Whitney Main trail cables on the switchbacks,yes they are left up year round.When the snow gets to a certain point the cables are buried and are by passed in favor of the bowl to the North.I have never heard of the cables being taken down like at Yosemite which maybe where you have heard about cables being removed.
The Whitney cables appear to be sunk into concrete and are fairly permanent now. I am not sure about the history though. There are several who can answer that question.
