“Take only pictures, leave only footprints” (parks policy)

“Take only pictures, leave only footprints” is a saying that has appeared on park signs and literature, instructing visitors to cause as little harm to the environment as possible. The saying appears to date to the 1950s, first popularized in California and other western states.
 
“Take nothing but pictures, leave nothing but footprints, kill nothing but time” was cited in print in 1971.
