The National Park Service is grouped into 32 Inventory and Monitoring networks across the country which are tasked with gathering and analyzing information on park resources. In 2018, each network created a short film to showcase some of the science that is being done in our parks. For the North Coast Cascades Network, some of the monitoring work being conducted at Lewis and Clark National Historical Park was chosen as the subject of this short film. Park staff assisted filmmaker Michael Durham and NCCN I&M Program Manager Dr. Mark Huff in the creation of this film. In it, we highlight the traditions of scientific observation and data collection that began here with the journals of Lewis and Clark and continue today through the use of modern technologies.
