First of all you have a great image of Horsetail Falls. This has been a record winter that is bringing plenty of rain to Yosemite Valley and snow the higher elevations. You timed it well in that most of February, or a lot of it, has been cloudy. Prior to the age of social media, Horsetail Falls was not the BIG event it has become. Unfortunately, during nights of The Event, there becomes a blockage of traffic making the ride out of Yosemite Valley very long! Still, February can be a wonderful time to photograph Yosemite Valley because of the low angle of the light. And combine that light with a dump of snow and we are in Heaven.
