In this image, Yosemite Creek may be seen just below the base of Yosemite Falls. Yosemite Creek is a 31.2 mile long creek in Yosemite National Park. It eventually joins with the Merced River in Yosemite Valley.

In this image, a landslide may be seen in detail below Moran Point in Yosemite Valley. The broken rock fragments are often referred to as talus deposits or scree.

In this image, a detailed view Upper Yosemite Falls may be seen from the Yosemite Falls Trail. Upper Yosemite Falls has a total plunge of 1,430 ft (440 m). Yosemite Falls is one of the most famous waterfalls within Yosemite National Park.

In this image, a large pinnacle may be seen adjacent to Yosemite Falls. Pinnacles form as the granite is weathered away via ice, water, or plant growth.

Manzanita bark is one of the shrub's most distinguishing features. New bark is smooth and red, while older bark becomes weathered by sunlight to light gray or white.

In this image, the east side of El Capitan may be seen beneath several jet contrails. El Capitan is a granite monolith that rises about 3,000 ft (900 m) from the valley floor and is one of Yosemite National Park's most famous landmarks.

In this image, the south side of El Capitan may be seen. El Capitan is a granite monolith that rises about 3,000 ft (900 m) from the valley floor and is one of Yosemite National Park's most famous landmarks.

Through breaks in the trees, talus deposits may be seen along the valley walls of Yosemite Valley. Talus deposits, also known as scree, are collections of broken rock fragments that have accumulated over time as rock weathers and breaks off from the cliffs above. This process can occur via various mechanisms, including ice, topographic stress, and plants.

In this image, the south side of El Capitan may be seen as fog clears around it. El Capitan is a granite monolith that rises about 3,000 ft (900 m) from the valley floor and is one of Yosemite National Park's most famous landmarks.
