In Yosemite, the scene is ever changing and may never appear the same twice. John Muir called this grand show eternal, with sunrise always somewhere, dew never all dried at once, a shower forever falling, and vapor ever rising as the round earth rolls through eternal sunrise, sunset, dawn, and gloaming. Through the seasons and at different times of day, summer brings clouds gliding among granite peaks, fall spreads autumn hues across maple and oak trees on the Valley floor, winter snow accents the subtle details of granite walls, and spring restores ephemeral waterfalls and the echo of rushing throughout the Valley.
