What country does the Doñana National Park and Caldera de Taburiente National Park have in common?
Caldera de Taburiente National Park Caldera de Taburiente National Park (Spanish: "Parque Nacional de la Caldera de Taburiente" ) is large geological feature on the island of La Palma, Canary Islands, Spain. It contains the enormous expanse of the Caldera de Taburiente which dominates the northern part of the island, and was designated as a national park in 1954. The telescopes of the Roque de los Muchachos Observatory are situated very close to the summit.
Saguaro National Park Saguaro National Park in southern Arizona is part of the National Park System in the United States. The park land consists of two distinct areas—the Tucson Mountain District (TMD) west of the city of Tucson and the Rincon Mountain District (RMD) east of the city—that preserve Sonoran Desert landscapes and diverse fauna and flora, including the giant saguaro cactus. The volcanic rocks on the surface of the TMD differ greatly from the surface rocks of the RMD; over the past 30 million years, crustal stretching associated with the Basin and Range displaced rocks from beneath the Tucson Mountains to form the Rincon Mountains. Uplifted, domed, and eroded, the Rincon Mountains remain significantly higher and wetter than the Tucson Mountains, and the higher elevations of the RMD support plant and animal populations that do not exist in the TMD.
