Saguaros & Rock Art

To most of the world, these prickly giants symbolize the American West. To me, they seem like a large family, gathered together after a long time of absence, merrily chatting away. Their posture, their gestures – expressive, daring, even obscene, the way they lean on each other; I feel at home among the Saguaros, never mind our differences (mainly in size).

We traveled a long way to meet them, because they gather exclusively only in small parts of the U.S. West; Tucson is one of their favourite spots, especially for the ”younger” among them.

Did you know that their branches begin to grow when saguaros reach 60 to 75 years of age? That is for those growing in the Saguaro National Park; in areas of lower precipitation, it may take up to 100 years before arms appear.

An adult saguaro is generally considered to be about 125 years of age. It may weigh 8 tons or more and be as tall as 50 feet. The average life span of a saguaro is probably 150 – 175 years of age. However, biologists believe that some plants may live over 200 years. The estimated number of saguaros in the Saguaro National Park is 1.8 million.

With such a long lifespan, it is only fitting that Saguaros would have chosen to gather here, in a land dotted with archeological sites spanning more than 8,000 years of prehistoric and historic-period occupation.

One of these prehistoric sites, accessible to visitors, is Signal Hill; a small hill with petroglyphs created by the prehistoric Hokoham people on the boulders that cover the hillside. Saguaro National Park, Tucson, AZ
