Robert Glenn Ketchum (born 1947) continues his exploration of Alaska, now focusing on one of the most significant watersheds in the world. The Wood-Tikchik State Park, a vast wilderness, is home to moose, grizzly bears, eagles, salmon, and one of the largest species of rainbow trout in the world. Accessible only by boat, plane, or on foot, these wild lands are nevertheless vulnerable to commercial exploitation.

Ketchum's stunning images immerse viewers in the extraordinary detail, color, and scale that defines this relatively unknown world of tundra and boreal forests, offering readers the unique experience of understanding the need to preserve this special ecosystem.

In his accompanying essay, Bill Sherwonit provides an excellent account of the historical use of the park and makes a compelling case for protecting one of North America's most important watersheds from fragmentation and unnecessary development.
