This climb is not very well protected and is easily toproped from the chains on top of Potholes.
It starts on the southeast edge of Red Spire about 20 feet to the left of Potholes. From there, it moves up and to the right past one old pin, over a small ledge to another pin, then finished out on the same last moves as Potholes. While I like this climb better than Potholes because it is a lot more face climbing and you run less of a risk of sticking your hand in something that really doesn't smell very good (like on Potholes), I must say doing it as a toprope the first time as opposed to leading it right off the bat would be wise.
Rap east from the chains on top of the spire.
Protection
This route is best toproped from Potholes, otherwise take a pair of quicks for the two pins, some smaller tricams for psychological protection, and something to tie into the chains on top.
Oops, my bad, I got my mountains crossed. Rap East off the chains on the top, not west, same for potholes. West would take you down between Red and White Spires and is not a good idea.
This description actually sounds like Incline Ledge. The South Ridge of the Red Spire starts just left of the true south ridge and climbs up to and over the roof on the direct south ridge, then continues on easier climbing to the summit.
