I visited the Signal Hill site in Saguaro National Park on the morning of November 28, 2017.  I had hiked King’s Canyon in the park at first light, then headed over to Signal Hill.  It is not a large site, but it has some interesting rock art and I am glad I took time to visit.  The signature element is a large spiral on a rock located on the top of the hill.  The light was not great for photography that morning, but I did my best.  Hope you enjoy my photos of this interesting little rock art site.  To see the blog I posted about the trip that includes my visit to Signal Hill, click here.
