Horsetail Fall at sunset, Yosemite. I had this view to myself When I made this image near Northside Drive back in 1995. How things have changed!
Yesterday the National Park Service issues a press release announcing a new permit system for viewing Horsetail Fall. Here are the essentials:
– From February 12th through 26th there will be a special “event zone” between Yosemite Valley Lodge and the El Capitan crossover.
– During that time Southside Drive will be open to two-way traffic, with no parking allowed between the El Cap crossover and Sentinel Bridge.

Horsetail Fall season will be here soon. The best light occurs from around February 16th through February 23rd. During that time, if conditions are right, the waterfall is backlit by the setting sun, while the cliff behind it is in the shade, creating dramatic color and contrast.
Before February 16th, Horsetail can get beautiful sunset color, but the cliff behind it is still in the sun. After February 23rd, the sunlight gets cut off before it reaches its deepest color. Of course the angle of the sun doesn’t change dramatically between the 15th and the 16th, or between the 23rd and the 24th, so it’s possible to capture good images of Horsetail Fall a few days before or after that window. But that period between the 16th and 23rd is, as far as I can determine, the optimal time. (See this post for an in-depth discussion about the timing of this event.)
Moon setting over Yosemite Valley and Horsetail Fall, spring of 2017
Every year, around the third week of February, the sun sets at just the right angle for Horsetail Fall. With clear skies and enough water, the backlit waterfall glows with a brilliant orange color, lit by the setting sun.
Some years ago it occurred to me that the setting moon could create the same effect. In the spring of 2010 I had a chance to try this, and it worked beautifully. As I wrote back then, I walked up to one of my favorite Horsetail Fall viewing locations early in the morning, and saw an amazing sight: that beautiful, low-angle backlight on the waterfall, with the cliff behind it in the shade. It looked like sunset in February, only with stars in the sky above it. And the camera captured what my eyes couldn’t see – the orange glow created by the setting moon:

It looks like there should be plenty of water in Horsetail Fall this month. Yosemite Valley has received almost ten inches of rain over the past week, and that abundant rainfall has boosted the flow in all of Yosemite’s waterfalls, including Horsetail. In fact the Merced River reached minor flood stage Wednesday night. While the rain runoff will diminish quickly, there’s a healthy snowpack at the higher elevations of Yosemite, which should keep Horsetail flowing for awhile. I expect above-average flow in Horsetail this year.
But water flow is just one element. You also need the sun to set at the right angle to backlight Horsetail and make it turn orange, yet have the cliff behind it in the shade, so that the glowing, backlit, orange water is set against a dark background. My best estimate is that this happens between February 16th and 23rd, and perhaps even a few days beyond. (I delve into more detail about all that here.)
El Capitan and Horsetail Fall at sunset, Yosemite
I rose early yesterday morning to go up to Yosemite Valley, thinking the storm might clear just after sunrise. But showers persisted, and the sun didn’t break through until almost ten o’clock. By the time I finished photographing it was almost noon, so I decided to stay in the valley until sunset.
In the afternoon typical after-storm condensation clouds formed around the rim of the valley. Thinking those clouds might add something to a photograph of Horsetail Fall, and allow me to capture something a little different from my other images of this waterfall, I headed for a spot with a good overall view of El Cap and Horsetail.
