Please feel free to contact me directly with any questions or concerns. Thank you in advance. It is unlikely to bother you, but Mirror Lake is actually misnamed. An informative panel by the lake explains that. Mirror Lake was once regarded by park scientists as a stream-fed lake slowly filling in to become a meadow. As hydrologists have developed a more complex understanding of the waters dynamics, they now theorize that the lake is a pool in a seasonal stream. Changes in the volume and speed of the streams water cause sand to be deposited and scoured from the pool in cycles. Correcting the name to Mirror Seasonal Stream Pool seems unlikely, but the good news is that Mirror Lake is no longer expected to completely fill with sediment. Mirror Lake was created by a fortuitous rock fall, as another panel explains. Perhaps only three or four hundred years ago, an enormous rockfall dumped boulders across this canyon, damming Tenaya Creek. During spring and early summer, the stream backs up into the two pools on either side of the dam. Nineteenth-century tourists admired the reflections on the surface of the upper pool of Mirror Lake. To enlarge the pool and reflection, early entrepreneurs piled boulders onto the natural dam. Ironically, this helped the pool fill with sand and silt, leading to the regular dredging of the lake. Today, the National Park Service maintains Tenaya Creek and Mirror Lake as natural systems. Sediment continues to build in the upper pool, which is gradually becoming shallower. The force of springtime water scours out most deposits in the undammed lower pool. Ansel Adams (born in California) was an American photographer who was the most important landscape photographer of the 20th century. He is also perhaps the most widely known and beloved photographer in the history of the United States; the popularity of his work has only increased since his death. Adamss most important work was devoted to what was or appeared to be the countrys remaining fragments of untouched wilderness, especially in national parks and other protected areas of the American West. He was also a vigorous and outspoken leader of the conservation movement. The item “Ansel Adams, Mirror Lake, Yosemite, Marker Signed Photograph” is in sale since Wednesday, April 29, 2020.
