The Caribou Mountains of northern Alberta dominate this late summer image, where deciduous foliage on the cusp of autumn’s …turn gives the splashes of yellow-green. The large river is the Peace, and nearby wheat fields are the continent’s most northerly commercial scale agriculture. The image’s upper half is within the Wood Buffalo National Park, where the bison gained its new lease on species survival in the last century. In the upper left are salty flatlands which the only Whooping Crane population uses as its nesting ground, before each year wintering in south Texas.
