when did the great sand dunes become a national park
Great Sand Dunes National Park and Preserve The idea that the dunes could be destroyed by gold mining or concrete manufacturing alarmed residents of Alamosa and Monte Vista. By the 1920s, the dunes had become a source of pride for local people, and a potential source of tourist dollars for local businesses. Members of the P.E.O. Sisterhood sponsored a bill to Congress asking for national monument status for Great Sand Dunes. Widely supported by local people, the bill was signed into law in 1932 by President Herbert Hoover. Similar support in the late 1990s resulted in the monumentâ€™s expansion into a national park and preserve in 2000-2004.[11]
Rocky Mountain National Park The Rocky Mountain National Park Act was signed by President Woodrow Wilson on January 26, 1915, establishing the park boundaries and protecting the area for future generations.[2] The Civilian Conservation Corps built the main automobile route, Trail Ridge Road, in the 1930s.[2] In 1976, UNESCO designated the park as one of the first World Biosphere Reserves.[6] In 2017, more than 4.4 million recreational visitors entered the park.[7] The park is one of the most visited in the National Park System, ranking as the third most visited national park in 2015.[8]
