The Half Dome cables in Yosemite National Park will be taken down for the season on Tuesday, October 9, 2012.
The cables are taken down each October for the fall and winter season.
The cables are proposed to be put back in place in the spring of 2013, as conditions permit.
Visitors are strongly advised against attempting to summit Half Dome without the cables in place as the dome can be extremely slippery and may be wet and/or icy even in seemingly dry conditions.
