Zion National Park: Acoustical Monitoring Summary Report

This report presents acoustical data that were collected at Zion National Park (ZION) between 2000 and 2008. Data were collected to provide park managers with information about the acoustical environment, noise sources, and to provide an estimate of natural ambient sound levels throughout the park. This report synthesizes the results from several data collection efforts by presenting figures, tables, and descriptions of the data; it does not attempt to make recommendations or draw management conclusions.
