2024 Map of Astoria

South across Youngs Bay, the map transitions into the lowlands of Warrenton and the riparian networks of the Youngs River and Lewis and Clark River. This area is defined by numerous sloughs such as Cook Slough and Jeffers Slough, which weave through small settlements like Jeffers Garden and Miles Crossing. Extensive protected lands, including the Lewis and Clark National Historical Park, preserve the marshes and forests that have shaped this region's character since the earliest days of exploration.
