The beautiful, 145 mi long Merced river flowing from the Sierra Nevada to San Joaquin Valley in California has helped create the panoramic, 8 mi long Yosemite Valley. This picture is from the base of Vernal Falls where the river flows calmly. It was quite a transition – from the thunder of the Falls to the serenity of the quietly flowing river – as if all the aggression had dissolved and everlasting peace was attained.
