Thank you for your comment. Hope you can go there too in the future! I traveled in many countries during the last 10 years, and Grand Canyon is one my "top places", especially because it was winter (so less people).
Thank you for your message. I only visited Grand Canyon in winter and you're right, there no haze during this season. Some of my friends visited it in summer and I could see in their picture that everything was like "burned" by the sun. Definitely loved to do it in winter, with amazing storms and lights !
