Sierra Wave, Owens Valley and Eastern Sierra, California, US
The Sierra Nevada is prone to create lenticular clouds, forcing winds to rise, resulting in condensing water vapor. Due to the length of that mountain range, a really impressive sight, and hopefully combined with evening colours.
This particular picture was taken during our Eastern Sierra workshop which I mentioned before. Not happy with spots using reflections of the Owens River, I ended up shooting along the valley, horizon really low. I liked that group of trees creating a middle ground. And for a sense of scale, the Eastern Sierra range visible on the right rises roughly 3,000 m (~10,000 ft) above the valley floor.
