Texas Parks and Wildlife (1970) : 38x17

Travel the Colorado River with biologists searching for a rare native fish, the blue sucker. From the surf and dunes of the Gulf to the bay side's quiet marsh and native prairie, Galveston Island State Park holds a lot to discover. As green sea turtles show up on Texas beaches in larger numbers than ever, a network of people step in to rescue stuck or stranded turtles.
