Ice Age glaciers played an essential role in shaping Yosemite’s landscape. Most of this ice had melted away due to natural warming by about 10,000 years ago. During a more recent cold period called the Little Ice Age, small glaciers formed below the highest peaks. Currently, two remain: the Lyell and Maclure glaciers.

2023年8月22日 · The Yosemite region has been at the forefront of North American glacier research for more than 150 years. This area served as a natural laboratory to legendary geologists like Josiah D. Whitney, Joseph LeConte, John Muir, Francois Matthes, and more.

2024年11月22日 · Yosemite's landscape would not be the same without the imprint of glaciers. Landforms that are the result of glaciation include glacially polished granite, U-shaped canyons, jagged peaks, rounded domes, waterfalls, moraines, erratics, and glacial lakes.

Today in the higher portions of Yosemite National Park, small-scale evidence of Ice Age glaciers can still be seen. Grooves and scratches in the Valley's bedrock, known as "striations," are evidence that glaciers scoured and gouged their way through the valley.

2022年5月3日 · Yosemite’s Living Glaciers. Despite global warming, a few small glaciers remain in Yosemite just below the crest of the Sierra. Scientists call them “living” glaciers because they continue to creep downhill. The ice sheets are products of the Little Ice Age, a period of mild, worldwide cooling that occurred from the 16th to 19th centuries.

The mountains, valleys, granite cliffs, waterfalls, and glaciers of Yosemite have inspired people for generations, including photographer Ansel Adams, naturalist John Muir, and countless hikers and rock climbers.

2016年10月14日 · Whether you’re gazing down Tunnel View, bouldering in Tuolumne Meadows, or taking a break beside an alpine lake, you’re immersed in a dynamic landscape sculpted by mountain uplift, rockfalls, and, of course, glaciers on granite. Top …

This map shows the extent of alpine icefields and associated valley glaciers in Yosemite National Park and vicinity during the most recent large glaciation, known as the Last Glacial Maximum, a globally recognized cold period characterized by low sea levels and the growth of ice sheets and mountain glaciers.

2018年9月25日 · Thousands of years ago, massive glaciers carved the Sierra landscape into what we know today. Slow-moving ice shaped valleys and cliffs, polished granite slopes, and left behind kettle lakes, moraines, erratic boulders, and leaping waterfalls.

2019年7月10日 · This map shows the extent of alpine icefields and associated valley glaciers in Yosemite National Park and vicinity during the most recent large glaciation, known as the Last Glacial Maximum, a globally recognized cold period characterized by low sea levels and the growth of ice sheets and mountain glaciers.
