Ones from the USA Holiday Archive. These particular images I think about when I reflect on my trip to Zion National Park in Utah. Amazing nature carved into a canyon over billions of years and amazing sunsets causing the mountains to glow red.
both were taken with the humble Tamron 17-50mm f2.8 on my Canon 50D. Both were taken on tripod with mirror lock up to retain the best image sharpness.
