Yet another excellent article on the beauty of Arizona by Roger Naylor.
“The San Pedro River supports some of the richest wildlife habitat in the Southwest,” says Laura Mackin, bookstore manager at San Pedro House. “This river of life provides resting places for millions of migratory birds and year-round homes for many kinds of plants, fish, reptiles, birds and mammals. In addition, the river supports one of the largest cottonwood-willow canopies remaining in Arizona and is one of the last free-flowing rivers in the Southwest.”
