Except for occasional rain, this is a quiet time of year at Tohono Chul Park. Not many visitors, few migrating birds, most snakes keeping to the shade. But there is still beauty everywhere. And sometimes excitement (see this August post from 2011).
One of my favorite fountains in the Park, the Pot Wall, in the Riparian area.
And throughout the Park, barrel cactus are blooming, each plant with a different color.
