The Sierra Club has bestowed wildlife photographer Steven Kazlowski with its Ansel Adams Award for his "superlative use of still photography to further a conservation cause." He was presented with the award at the Sierra Club's national dinner on Sept. 20.

Kazlowski's images have appeared in magazines such as Vanity Fair, Newsweek and Canadian Geographic. His recent book, "The Last Polar Bear," published by Braided River, is an eye-opening look at the changing landscape in the Arctic regions and what climate change means for its animal inhabitants.

Braided River, the conservation imprint from The Mountaineers Books, in conjunction with the University of Washington's Burke Museum, has also developed an exhibit revolving around Kazlowski's works on display through Dec. 31.
