The U.S. Army Corps of Engineers Sacramento District observed the 21st annual National Public Lands Day at eight of its parks in central California. The Corps has been involved with National Public Lands Day since its inception in 1994 and has consistently been one of the largest providers of sites and volunteers participating in the event. This event also supports President Barack Obama's America's Great Outdoors Initiative, an effort to promote the conservation of outdoor spaces and reconnect Americans to the outdoors.
