Which small rabbit relative of Rocky Mountain National Park's high rock piles dries 'haystacks' of plants instead of hibernating?

American pika: about the size of a hamster, it never hibernates and stays active in tunnels under the snow, so it spends the short summer cutting plants and stacking them to dry.

Which road across Rocky Mountain National Park is the highest continuous paved road in the United States?

Trail Ridge Road tops out at 12,183 feet, high enough that deep snow shuts its upper stretch each autumn; ploughs usually reopen it around Memorial Day.

Rocky Mountain National Park's high road tops out at 12,183 feet, above the highest summit of which of these states?

Which bark-boring insect has killed vast stands of conifers in Rocky Mountain National Park since the 1990s?

Mountain pine beetle: deep winter cold used to kill most of its eggs and larvae under the bark, but milder winters have let far more survive, and whole hillsides of pines have died.

What dumped the boulder-strewn alluvial fan in Rocky Mountain National Park's Horseshoe Park in a single morning in 1982?

A dam failure: the old earthen dam at Lawn Lake gave way high above, and the flood roared down the Roaring River, killing three people and dropping its load of rock and gravel where the ground levelled out.

As of 2026, what do most summer daytime visitors need, besides a pass, to drive into Rocky Mountain National Park?

A bear canister is the required food storage at backcountry camps below treeline from April to October; the park has just a few dozen black bears, and one that learns to raid camps for human food is often killed.

Which pine of Rocky Mountain National Park has resin-sealed cones that the heat of a wildfire opens?

Lodgepole pine keeps many of its cones glued shut for years; a fire's heat melts the resin and frees the seeds onto sunny, cleared ground, which is why burned slopes here can grow back as almost pure stands of it.

Above roughly 11,000 feet, about a third of Rocky Mountain National Park is covered by which Arctic-like ecosystem?

Alpine tundra begins where wind and cold stop trees from growing; its plants hug the ground and grow so slowly that a trampled patch can take hundreds of years to recover.

What is the name for the stunted, wind-twisted trees that grow at Rocky Mountain National Park's treeline?

Krummholz, from the German for 'crooked wood': seedlings sprout in the lee of rocks and can grow only as tall as that shelter, so they spread sideways into dense mats that may live for centuries.

Which silver-mining camp of the early 1880s is now a ghost town in Rocky Mountain National Park's Kawuneeche Valley?

In Rocky Mountain National Park place names such as Moraine Park and Horseshoe Park, what does 'park' mean?

A broad mountain valley: in the Rockies 'park' is a regional word for a level, grassy opening between the ranges, which is why North Park and South Park are basins rather than preserves.

Ypsilon Mountain in Rocky Mountain National Park takes its name from what Y-shaped feature on its east face?

A snowfield: in the 1880s a visiting climber's wife saw two bands of ice run up from it to the ridge in a perfect Y and declared, 'Its name shall be Ypsilon Peak.'

Lumpy Ridge in Rocky Mountain National Park kept its rounded granite domes because which erosive force never reached it?

Glacial ice carved most of the park's valleys but stopped short of Lumpy Ridge, so slow weathering alone rounded its granite into shapes such as the Twin Owls.

What started the 1978 fire that Rocky Mountain National Park at first let burn?

Lightning lit it in Wild Basin, and under a new policy of leaving natural fires alone it was only watched; weeks later strong winds drove it toward the town of Allenspark and about 500 firefighters had to be called in.

Rocky Mountain National Park's last small glaciers, such as Andrews and Tyndall, survive in which bowl-shaped hollows high on the peaks?

Cirques are the steep-walled bowls that far larger Ice Age glaciers gouged at the heads of the valleys; Chasm Lake, below the park's highest peak, fills one of them.

Which mountain-building event, beginning roughly 70 million years ago, raised the modern ranges of Rocky Mountain National Park?

The Laramide orogeny was the region's second act: an earlier range, the Ancestral Rockies, had risen roughly 300 million years ago and been worn down before the present peaks went up.

Which town lies at the western entrance to Rocky Mountain National Park?

Grand Lake stands beside a deep natural lake that Native legend held to be haunted, after a raft carrying families to safety during a battle broke up in a sudden storm.

Which streamside mammal of Rocky Mountain National Park was the main prize of the mountain men who trapped the Rockies?

Beaver pelts drew trappers into these mountains in the early 1800s; biologists call the animal a keystone species, because its dams turn streams into ponds and wetlands that shelter many other creatures.

A river rising in Rocky Mountain National Park is said to be named for snowbound French trappers burying what?

Gunpowder is the best-known of several tales: caught by heavy snow, the trappers lightened their loads by burying their powder beside the Cache la Poudre, French for 'hide the powder'.

Which burrowing rodent of Rocky Mountain National Park's high country posts a sentinel that whistles when danger is near?

Yellow-bellied marmot colonies spend the short summer eating and basking on the rocks, because they will pass more than half the year, about eight months, asleep in their burrows.

What name is given to the rising, squealing call of bull elk that draws autumn crowds to Rocky Mountain National Park's meadows?

Bugling starts deep, climbs to a squeal and ends in grunts; bulls use it during the autumn rut to warn off rivals, and the older the bull, the stronger the call.

Which range in Rocky Mountain National Park has peaks named after clouds, such as Mount Cirrus and Mount Cumulus?

The Never Summer Mountains, home to Mount Nimbus and Mount Stratus too, are an oddity in another way: they are the worn-down remains of volcanoes far younger than the ancient rock of the rest of the park.

Picnickers brewing coffee in 1900 started a two-month wildfire beside which lake, now a famous Rocky Mountain National Park trailhead?

Bear Lake's blaze, remembered as the 'Big Fire', grew from a log the picnickers thought they had put out; when the wind rose it flared up again and swept the surrounding forest.

Horace Albright made the promise while crews were still cutting the road; fifteen years earlier, as a young government assistant, he had helped set up the Park Service itself.

Rocky Mountain National Park has culled elk and fenced them out of wetlands because which predator was wiped out last century?

Gray wolf packs were hunted out of the state by the 1940s; without them the elk herd overgrazed the valleys, so trained shooters and tall fences now stand in for the missing predator.

What halted Rocky Mountain National Park's 2012 Fern Lake Fire after it had burned for two months?

A snowstorm in early December checked the fire, lit by an illegal campfire in October, after gale-force winds had driven it miles in a single night and forced evacuations; smoke was still rising in January.

Which songbird of Rocky Mountain National Park's streams walks underwater to hunt insects?

American dipper, also called the water ouzel, hunts like a diver: it bobs up and down on a rock in mid-stream, then wades in and walks along the bottom of fast, cold mountain water.

Which national forest borders Rocky Mountain National Park to the north and east?

Roosevelt National Forest was the Colorado National Forest until 1932, when a presidential order renamed it for Theodore Roosevelt to end the confusion of one forest among several carrying the state's name.

Which transport, vital to Grand Canyon tourism, never reached Rocky Mountain National Park, leaving it an 'auto park'?

Railroads stopped at foothill towns such as Lyons, so visitors finished the trip by stagecoach and later by car, and the Park Service made road building its priority here.

Rocky Mountain National Park's chief campaigner was inspired by an 1889 meeting with which conservationist?
