Sierra Nevada Challenge level: ★☆☆
1

Yosemite National Park is located primarily within which mountain range?

Correct answer: Sierra Nevada. Yosemite National Park lies in California's Sierra Nevada. Its high mountains, granite domes, deep valleys and glacially sculpted terrain form part of this major mountain range of the western United States. The park covers nearly 1,200 square miles of mountainous terrain and wilderness.
Yosemite Valley Challenge level: ★☆☆
2

Which river flows through and drains Yosemite Valley?

Correct answer: Merced River. The Merced River flows through Yosemite Valley and continues westward out of the Sierra Nevada. The river and its tributaries played an important role in carving the landscape even before glaciers later widened and deepened the valley. The Merced is one of two federally designated Wild and Scenic Rivers that begin within Yosemite National Park.
Yosemite Geology Challenge level: ★☆☆
3

Which type of rock dominates Yosemite's famous cliffs, domes and much of its bedrock?

Correct answer: Granite. Granitic rocks dominate Yosemite's geology. Granite is an intrusive igneous rock that formed when molten rock, or magma, slowly crystallized deep underground before uplift and erosion eventually exposed it. Yosemite's resistant granite helps preserve the bold cliffs and rounded domes for which the park is famous.
Ice Age Yosemite Challenge level: ★★☆
4

Which natural process was especially important in widening, deepening and shaping Yosemite Valley into its dramatic present-day form?

Correct answer: Glacial erosion. Rivers first cut valleys through the Sierra Nevada, but repeated Ice Age glaciers greatly widened, steepened and deepened the landscape. Their movement helped produce Yosemite Valley's classic broad, steep-sided glacial form. USGS describes Yosemite Valley as a classic U-shaped glacial valley.
Half Dome Challenge level: ★★☆
5

Which geologic process helped give Half Dome its characteristically rounded granite surface?

Correct answer: Exfoliation. After erosion removed overlying rock, pressure on the underlying granite decreased. This allowed sheets of rock to separate through a weathering process called exfoliation, contributing to Half Dome's rounded appearance. Weathering along vertical joints and later glacial erosion also helped produce Half Dome's steep northwest face.
Mariposa Grove Challenge level: ★☆☆
6

Mariposa Grove, Yosemite's largest grove of its kind, protects more than 500 mature examples of which enormous tree?

Correct answer: Giant sequoia. Mariposa Grove is Yosemite National Park's largest giant sequoia grove and contains more than 500 mature giant sequoias. These trees are among the most massive living organisms on Earth. The famous Grizzly Giant in Mariposa Grove is estimated by the National Park Service to be around 3,000 years old, give or take several centuries.
Yosemite Falls Challenge level: ★★☆
7

What is the approximate total height of Yosemite Falls when its three sections are combined?

Correct answer: 2,425 feet. Yosemite Falls drops a total of approximately 2,425 feet, or about 740 meters. It consists of Upper Yosemite Fall, the middle cascades and Lower Yosemite Fall. The National Park Service lists Upper Yosemite Fall at 1,430 feet, the middle cascades at 675 feet and Lower Yosemite Fall at 320 feet.
Yosemite High Country Challenge level: ★☆☆
8

Which Yosemite high-country destination is a large subalpine meadow crossed by the winding Tuolumne River?

Correct answer: Tuolumne Meadows. Tuolumne Meadows is a broad subalpine meadow in Yosemite's high country. The Tuolumne River winds across the meadow while granite domes and Sierra Nevada peaks rise around it. The Tuolumne and Merced rivers both originate within Yosemite National Park and flow west toward California's Central Valley.
Yosemite Grant Challenge level: ★★☆
9

Which U.S. president signed legislation in 1864 protecting Yosemite Valley and the Mariposa Grove for public use and recreation?

Correct answer: Abraham Lincoln. President Abraham Lincoln signed the Yosemite Grant on June 30, 1864, during the Civil War. The legislation protected Yosemite Valley and the Mariposa Grove and entrusted them to California for public use, resort and recreation. The Yosemite Grant became an important milestone in the development of the American idea of permanently protecting scenic landscapes for public benefit.
National Park History Challenge level: ★★☆
10

In what year was Yosemite formally established as a United States national park?

Correct answer: 1890. Yosemite National Park was established on October 1, 1890. This expanded federal protection to a much larger area of Yosemite's surrounding mountains and forests. The earlier Yosemite Grant of 1864 had already protected Yosemite Valley and the Mariposa Grove, but Yosemite did not become a national park until 1890.
