60 free Mount Rainier National Park trivia questions with answers — geography quiz, new questions added Aug 2026.
This Mount Rainier National Park trivia quiz covers the 1899 park that wraps a 14,410-foot glaciated volcano an hour and a half from Seattle. It ranges over the developed areas (Paradise, Longmire, Sunrise, Ohanapecosh and the Carbon River rainforest), the record-setting snow at Paradise, the 93-mile Wonderland Trail, and the glaciers that give the mountain the biggest ice cover of any peak in the lower 48. There is plenty of history and geology too: George Vancouver naming the peak for a Royal Navy friend, the long fight over 'Tacoma' versus 'Rainier', the 1870 first ascent and Fay Fuller's 1890 climb, the Osceola Mudflow that sheared off the old summit, the lahar sirens that now guard Pierce County, and the 1947 sighting over the mountain that gave the world the phrase 'flying saucers'. Questions run from easy to expert with the difficulty shown on each one, so it works for a car game on the drive to Paradise or a serious park-nerd challenge. Every answer was checked against a reference page and each question carries its citation. If you enjoy it, try our Yellowstone, Grand Canyon and US National Parks quizzes next.

Q 07What summit elevation do the National Park Service and USGS officially cite for Mount Rainier?
14,410 ft
Recent surveys suggest the Columbia Crest icecap has melted enough that a bare-rock point on the southwest crater rim may now be the true high point.

It opened on July 1, 1917, having cost between $90,000 and $100,000, and was declared a National Historic Landmark in 1987.
Q 23What roof colour did the Park Service insist on for a 1916 south-slope park inn, rejecting the planned red?

Panhandle Gap
In many years the trail is still mostly buried in snow through June and early July.
Q 18Roughly what share of the climbers who attempt Mount Rainier's summit each year actually reach it?
About 50%
Weather and the climber's physical conditioning are the most common reasons for turning back on the two-to-three-day climb.
Q 19Which area does the National Park Service call 'the snowiest place on Earth where snowfall is measured'?
Paradise
At about 5,400 feet on the south slope, it averages roughly 640 inches of snow a year, and the snowpack often lingers in the meadows into July.
Q 20How much snow fell at the park's snowiest station in the record 1971-72 season?

A mineral spring
A 1924 park publication counted some forty distinct springs there, all highly carbonated and 'extremely hard'.

National Park Inn
It sits at Longmire, 6.5 miles inside the Nisqually Entrance among old-growth Douglas fir, red cedar and hemlock.

Ohanapecosh
It compensates with hot springs, Silver Falls and the Grove of the Patriarchs, all in the park's southeast corner.

Carbon River
The road beyond the entrance washed out in the 2006 floods and has stayed closed to cars ever since.
Q 30What is the largest and deepest lake in Mount Rainier National Park?
Mowich
It is also a common starting point for the loop trail around the mountain and the high alternative route through Spray Park.
