Colten, C. E., & Dilsaver, L. M. (2005). The hidden landscape of Yosemite National Park. Journal Of Cultural Geography, (2), 27. Retrieved from http://ic.galegroup.com/ic/whic/AcademicJournalsDetailsPage/
The author, professor of Geography at Louisiana State University, examines the infrastructure of national parks, mainly water, sewer, and garbage services. The paper traces the gradual adoption of romantic-era concepts about shielding human intrusions in parks from public view by Park Service landscape designers during the early twentieth century. He also examines how the U.S. Parks Department has drafted formal guidelines for continuing to keep these services out of public view. This article is relevant to my topic since it provides a detailed, historic policy overview of Yosemite and supports my argument that Yosemite needs more creative ways to deal with increased visitor traffic. This article augments my other sources by providing a background to current Yosemite infrastructure policy.
