Happy 125th birthday to #Yosemite #NationalPark! On this day in 1890, Congress created @yosemitenps, which is best known for its towering granite monoliths and breathtaking waterfalls.

6. Reflections Canyon

#ReflectionCanyon is one of the unique wonders in the #Southwest. Located in a remote section of #GlenCanyon National Recreation Area in #Utah, Reflection Canyon offers unparalleled views of the #ColoradoRiver twisting and winding through colorful sandstone cliffs. After the tough hike to reach Reflection Canyon, photographer Wan Shi was rewarded with this spectacular shot. “This has to be the most colorful and surreal scene I have ever seen in American Southwest.” Photo by Wan Shi.

7. Isle Royale National Park

Enter the quiet of the boreal forest and wander beneath spruce and fir trees. Perch on a rock and experience #LakeSuperior’s moods, which shape and change the area’s rugged shoreline. After a day of kayaking, explore the night sky and witness the #MilkyWay sparkling overhead. This is this northeastern end of #IsleRoyale #NationalPark in #Michigan.

12. Zion National Park

The Narrows is one of the most popular areas of Zion #NationalPark in #Utah, and we can definitely see why. #TheNarrows is surrounded by the soaring walls of the #Zion Canyon and spans 20-30 feet wide in parts. To get this great shot of The Narrows, Evan Kokoska (@evankokoska) started his day at 4 am -- early enough to hike to the part of The Narrows with good morning light and gorgeous fall colors.

13. Crater Lake National Park

18. Grand Teton National Park

One of the most beautiful and most photographed scenes in #GrandTeton #NationalPark in Wyoming is #SchwabacherLanding. On any given morning, a crowd will gather to shoot the reflection of the Teton Range in the quiet stream or beaver ponds. A few years ago, D. Brent Young was lucky enough to capture this amazing photo of a cow #moose feeding in the stream with fall color and the towering Teton peaks in the background. Photo of @grandtetonnps by D. Brent Young.

20. Kenai Fjords National Park

A trip to #Alaska wouldn’t be complete without seeing mountains, #glaciers and gorgeous blue water. #KenaiFjords #NationalPark has all three. The park sits at the edge of the North Pacific Ocean, where storm patterns develop and feed a land of ice. The #HardingIcefield crowns the park and is the source of at least 38 glaciers that flow over the land, sculpting as they go. Photo by Michael McRuiz.
