It turns out that the short dead-end road ends at a guzzler (a contraption for storing rain water for later use by wildlife)

To my surprise, I find a small stream in this unnamed Castle Peaks canyon
No spring is marked on my maps at this location, so I wasn't expecting to find any water between my tent and Indian Spring, my destination, on the other side of Castle Peaks. The water is clean and some bees are enjoying the stream's periphery.
