Focused around a redwood sapling in a public park in Portland, Time Capsule for a Tree is a community event to create a time capsule. Redwoods (and in this case, Giant Sequoias) can live to be 4,000 years old. A non-native species in Northwest Oregon, the trees are anticipated to do well as our climate changes. Participants gathered at the tree and were asked to imagine it at the height of its growth, 2,000 years into the future. Responding to the prompt, “What would you like future residents to know?” Participants left behind a message to future inhabitants. The documents are registered in a ledger and will be buried at the roots of the tree. Participation was celebrated through a commemorative letter-pressed certificate, with language adapted from the commemorative book announcing the Westinghouse Time Capsule sealed at the site of the 1939 World’s Fair. The Time Capsule for a Tree will be exhumed in the year 4,019. In the present the tree will serve as a reminder to participants and park goers of the many potential futures of the place and its inhabitants.
