On rare years when the conditions are right in the arid landscape of the Badlands, in the American West, wildflowers burst into a display of colour for just a few days.
The vegetation in the region has adapted to the climate, with just a small amount of moisture the desert can become coloured with sweeping fields of Scorpion Weed, Beeplant and the flowers of the Pincushion Cacti. These blooms can be very short-lived to conserve moisture.

Looking up from underwater, one sees the whole sky. But it doesn’t stretch 180 degrees from horizon to horizon like it does above water. Instead it’s compressed into a circle about 97 degrees across, regardless of the observer’s depth. This occurs because light rays bend when entering or exiting water. The shrunken sky seen by submerged observers is called Snell’s Window, informally named for Willebrord Snellius, a Dutch astronomer and mathematician. It’s also called the optical manhole.
