A big black bird that rolls and tumbles in the wind. Listen for a deep croak, not a crow's caw.

Ravens are some of the smartest birds alive. In tests they can "count" to about seven and solve puzzles, and young ravens do about as well as adult chimpanzees on some thinking tasks.

The park's largest free-standing arch, seen from the Upper Viewpoint across the canyon. The walk is 0.5 mile with stairs.

The freestanding arch on the Utah license plate: a 46 ft × 32 ft opening per NPS, roughly 52 ft tall, standing alone on a bowl of slickrock with the La Sal Moun…

Two black collars and a bright green body. It basks on sunny rock and may run on its hind legs.

A collared lizard can run on just its two back legs when it needs speed, tail out for balance, so it looks like a tiny running dinosaur crossing the rock.

A 306-foot ribbon, the longest natural arch in North America. The trail is 1.8 miles round trip.

The longest natural arch in North America, 306 ft per NPS, thinned to a ribbon at its middle.

Flat green pads with spines and yellow flowers in spring. Look, do not touch, and do not eat the fruit.

A prickly pear's flat green pads are not leaves, they are actually its stem. The pads do the plant's food-making and store water, while the real leaves shrank down long ago into the spines.

A 128-foot cap on a softer stem. Walk the 0.3-mile loop and look at the layer underneath.

A 128-foot formation: a caprock of harder Entrada Sandstone perched on an eroding pedestal of softer Dewey Bridge mudstone that wears out from under it.

A low cactus with scarlet cup-shaped flowers. The spines are short, and the plant is still off-limits to hands.

The claret cup gets its name from its flowers, which are shaped like little cups and are a deep red, the color of a drink called claret. A single mound can hold dozens of blooms at once in spring.

Two arches sharing one end, in the Windows section. A short sandy walk from the parking lot.

Two arches that share one end of their span, formed by water cutting down from a single pothole instead of sideways through a fin, a different mechanism than mo…

About a mile past North and South Window. The easiest big-arch loop for short legs.

A loop, mostly flat over packed sand and a few rock steps, past three large openings: North Window and South Window side by side in one fin (the "Spectacles"),…

Big ears, a black-tipped tail, and a bouncing run. Watch the rim at dusk.

Mule deer are named for their ears, which are about three-quarters as long as their whole head. Those big ears catch faraway sounds and also let heat escape to keep the deer cool in the desert.

A 0.4-mile walk into deep sand between two fins. Sit down and dig.

A 0.4-mile round-trip into a sandy slot between two tall fins that block the wind and most of the sun, so it stays cooler than the open trails.

More often heard than seen. Listen for a sweet whistle that falls down the scale.

Its song is a sweet, descending whistle that may be the only sign the bird is there.

The 0.5-mile walk with stairs, across the canyon. No need to climb to the arch itself.

How a family still sees Delicate Arch without the 3-mile slickrock climb.

Sit through the film before the first drive. It explains the salt, the cracks, and the water.

At Balanced Rock, name the soft layer under the cap: Dewey Bridge mudstone.

At the Wolfe Ranch panel, find the figures on horseback. Count the legs and the rider.

Stand behind North Window and frame Turret Arch inside the opening.
