While camping, we also visited Saguaro National Park, which is on either side of the city of Tucson - East and West. it was really neat to stroll down the little path and have these giant cactus towering over our heads! The taller they are, the older they are - some between 150-200 years old! The cactus are between 40-60 years old before the "branches" appear!
The above photo is one I really love! I love the contrast of the mountains in the background and the cactus in the foreground - not something this person from the Midwest ever thought really occurred!
And, finally, take a look at some of the pretty blooms that grow at the base of some of the saguaro cactus. Aren't they lovely - and a taste of summer in the midst of spring!
