Saguaro was not in our plan. In fact, I did not
even do any research during planning. I insisted to visit the park so we could
claim that we have been to all National Parks in Arizona.
Saguaro
The whole mountains of saguaro cacti.
We then found, after arrived, that this park is
all about cactus. In fact, Saguaro is the name of high cactus grown here.
Park ranger told us that Saguaro is habitat in Sonoran desert and this area
(nearby Tucson) is almost the north boundary of where it can live, because it is
too cold. He also told us that the day we visited was cool.
We bursted into laugh
because we knew that the temperature outside was around 102ºF.
The temperature at night time can and does drop sharply in the desert though.
By the way, the visitor center has a fantastic
slide show with great pictures and music. If you visit, make sure to watch it.
