Brian Aldiss' novel of a far future time when the Earth has one side constantly facing the sun.
This new series of caches is themed around some of the great science fiction novels. It will take you along a very nice part of the Alpine Trail in Portola Valley. All of the caches were placed within a few feet of the trail.
Please replace as found and beware of muggles. This trail can be quite busy at times. Cycling and hiking the trail are good choices. I suggest parking in the extended parking lot near the intersection of Alpine Road and Arastradero Road. There is very little legal parking in Portola Valley.
