This week we welcome in the first day of fall! This autumn photograph features the glacial melt that makes up Yosemite National Park’s primary river. The trees, whose colors are changing, line the banks of the Merced River while their reflection sparkles in the calm water. Milton Goldstein began photographing in his 50s after his first trip to Yosemite, which mesmerized him. His works focus on the National Parks in the west.
