I didn't see those when I climbed the Cables route in 1984!
There was a privy then, but it wasn't solar.
I sure didn't see it. Of course, we didn't see much of anything it was foggy and snowing like hell the whole time. Surprised we found the route. Sure was glad for the bulls eyes on the Keyhole route coming down. A good time was had by all!!! Yes!!!
A reading light?
The high definition, wide screen TV ... but, seriously, for the dehydration process.
