Still being built

Coming soon.

This site keeps growing. Here's what's still ahead — some of it planned from the start, some of it added since launch and not fully finished yet.

Field Scanner

Point your camera at a rock and get a real field-guide-style identification — not a black-box answer, but the actual visual clues behind the guess, plus the physical tests (streak, hardness, acid reaction) you can run yourself to confirm it.

Deep-Time Location Explorer

See where the ground under your feet actually sat hundreds of millions of years ago — pick a spot, move a slider through geologic time, and watch the continents rearrange around it.

Rock Layer Explorer

An interactive cross-section of the Grand Canyon. Click through 16 exposed rock layers, each one a snapshot of a different moment across nearly 2 billion years, with a direct link to that layer's rock type and its place on the geologic time scale.

More animated formation diagrams

Karakoram, Caucasus, Zagros, Scandinavian Mountains, and Southern Alps currently use photos and text like the rest of the site, without the hand-animated interactive cross-sections the original nine ranges have. Same treatment is planned for the Field Notes articles too.

Already live.
