Grand Lake serves as the gateway to this alpine landscape, where the waters of the Colorado River are managed through an intricate system of high-altitude engineering. The map details the proximity of Shadow Mountain Lake and the northern reaches of Lake Granby, illustrating how the Alva B Adams Tunnel and the Granby Pump Canal facilitate water movement across the continental shelf. These mid-century water projects reshaped the local geography, creating distinctive features like Rainbow Island, Gull Island, and Shelter Island within the newly formed reservoirs.
