Falling 2425 feet (730m) in three sections, Yosemite Falls is the tallest waterfall in North America and the fifth tallest in the world. During winter, a cone of frozen mist forms at the base of Lower Yosemite Falls. A strenuous hike takes visitors from the valley floor to the precipice of the falls, offering impressive perspective of the falls and their enormity relative to the valley itself. Yosemite Falls flows year round; May and June are most impressive, while flow slows to nearly a trickle during winter months.

Spring is the time to visit Vernal Falls and the famous Mist Trail in Yosemite National Park. Vernal Falls is at peak flow in late May and June, the weather is usually pleasant and the dogwoods are in bloom on the valley floor. We try to make a springtime visit to Yosemite each year to hike the Mist Trail with our daughters. We get soaked by the falls on the way up, soak in the sun and dry off at the top, enjoy a lunch of trail mix and Clif bars alongside other hikers, and leisurely make our way back down the trail later in the afternoon. If one times his visit to Vernal Falls at midday, a rainbow is often visible in front of the falls when viewed from the trail just 100 yards away.

On a recent visit to Utah I had a chance to spend some time in Zion National Park. A number of ephemeral waterfalls were flowing, the result of rainstorms that had passed over Zion Canyon a few days before. The Temple of Sinawava, a widening in Zion Canyon at the end of the paved road, featured a fine waterfall that I am told is typically dry but which had been seen most of the past winter and spring due to the amazing amounts of rain southern Utah has seen this year. That same morning I photographed two other emphemeral falls above nearby Weeping Rock. My tram driver informed me that those two almost never flow and that they were due solely to the rain that had fallen the preceding night and not to any snow melt, and that they would be dry by afternoon. Heavy cloud cover allowed for a long shutter speed, softening the appearance of the falls and accentuating the color in the rain-slicked red sandstone cliffs and cottonwood trees.
