I am also planning to start hiking this friday 10/15/15. Based off of the pictures other people have posted, YakTraks might be good up to Trail Camp but I would be very skeptical of their performance at any incline. I have used YakTraks on San Gorgonio (SoCal, 11,500ft) in the snow this January and regretted it. I was slipping on any ice that was not level. I highly suggest you pick up at least a pair of microspikes. I will be trying the Kahtoola MicroSpikes from REI the first time on this trip, but they look like they'll do the job and had great reviews.
