Wispy clouds float over Jackson Lake as the sun slowly sinks behind the Teton mountains at Grand Teton National Park in Wyoming. Snow still covers the towering, jagged mountains, but daytime temperatures are climbing into the 60s. Now that the roads are cleared, it’s a great time to explore the park.

Happy First Day of Winter! Snowy mountains are gorgeous, but can be challenging models. Casey Withers was recently at Grand Teton National Park in Wyoming trying to capture the sunrise. It was a cold morning and clouds were moving in. “This shot was set up originally as a test shot as we waited for sunrise, but three minutes later the mountains were covered. Glad I was prepared.” Photo courtesy of Casey Withers
