Caribou in the Brooks range mountains

Caribou on the mountain ridges of the Brooks range--all the little brown dots in the foreground, I'm guessing perhaps 1000 in this group.

Thanks to a generous friend, colleague, pilot, Hugh Rose, I spent an afternoon flying over the Brooks range looking at caribou along the mountain ridges. These are reportedly from the Porcupine caribou herd that migrates across the Brooks range and eventually reaches the calving grounds of Alaska's arctic north slope. Aggregations of 100 to 1000 animals could be seen feeding on the windswept mountain ridges where I presume access to food was a bit easier than the heavy snow-laden lowlands. The Brooks range is always an experience of immense wilderness. The mountains go on and on, with scarcely a node of human habitation. Conditions were far from optimal from almost every perspective but I grabbed a few photos that show how mobile and hardy this animal is, able to trek the high and low country and travel for miles. The vista of a large group of caribou migrating in a long line eluded us, although we saw many tracks revealing amazing photo ops if the timing was right.
