"[Last year] people flipped rocks on four continents on sites ranging from mountaintops to urban centers to the floors of shallow seas. Rock-flippers found frogs, snakes, and invertebrates of every description, as well as fossils and other cool stuff. [...] Be sure to replace all rocks as soon as possible after documenting whatever lies beneath them. Any and all forms of documentation are welcome: still photos, video, sketches, prose, or poetry. We encourage those of a scientific bent to try and identify everything they find, but we’re also open to purely lyrical or impressionistic responses." - Deirdre
