Off by default. Turning it on lets the image respond to your cursor with a shallow sense of depth, rebuilt from a depth map computed when the image was catalogued. It is an interpretation for looking, not a measured 3D model — and it falls back to the flat image where the browser can't render it.

On the image

Five million years of the Colorado River's work is visible here in a single glance, which is the Grand Canyon's most reliable trick: making every human timeline feel provisional. This is the Tonto Platform, the broad flat bench that sits partway down the canyon walls where ancient Tapeats Sandstone meets the talus, a landscape so geologically legible that every geology textbook has used some version of this view to explain what deep time actually looks like when you can walk around in it.

The dry wash threading through the foreground records a different kind of time — the flash-flood season, when this apparently peaceful gravel flat turns into something no hiker wants to be standing in. Prickly pear and desert scrub colonize the margins with the patient confidence of plants that have been outwaiting tourists since long before the National Park Service put up signs about them.

By 2002, the inner canyon trails had been walked by enough visitors that the NPS was spending considerable energy convincing people that a place this dramatic was also genuinely dangerous — a message the canyon itself communicates more efficiently than any brochure, simply by being a mile deep and offering no shade.
