Deep Time Cards

I remember the experience in San Francisco in 1997 at the State of the World Forum of doing the kind of deep time walk recorded in these 58 beautifully produced cards, one for every 100 million years up to the dawn of humans. Each card is beautifully illustrated and explains the history of the period. In addition, there is an overall timeline of the anthropocene with a further nine explanatory cards summarising our present situation, detailing the Earth Charter and assessing our prospects for the future. An app is also available but the cards are already an impressive experience to walk through.
