25 stunning photos of the great outdoors

From snowcapped mountains to sleepy city streets at dawn, the world is filled with awe-inspiring landscapes just waiting to be discovered.

We partnered with Olympus for this week's Mashable Photo Challenge, and asked you to send your most breathtaking photos of the great outdoors. Your submissions were outstanding, and included everything from surfboards and sunsets to beaches and bears.

Congratulations to Jamie Williams, who was chosen by Olympus and Olympus Trailblazer Alex McClure to win an Olympus Silver OM-D E-M1 Camera and Olympus M.Zuicko Digital ED 12 – 40mm f.2.8 PRO Lens.
