2. With an uncertain future ahead of them, Gene Brash and Bill Workman lead supply mules into the Bob Marshall Wilderness.
3. Above: Bill Workman and Gene Brash save about a mile and a half by fording the South Fork of the Flathead River just north of the Black Bear Camp. The vast Bob Marshall Wilderness is off-limits to motorized travel, except for emergencies. All supplies must be transported on the backs of mules to backcountry Forest Service crews.
4. The cabin at Black Bear Camp has only the essentials for living in the woods. The stove was air-lifted in before the Bob Marshall Wilderness was declared a wilderness area in 1964.

7. Right: As the sun starts to light the land around the Black Bear cabin, Brash returns for a cup of coffee after feeding the mules and horses.
8. Above: Mules are loaded with the everything the backcountry crews need, whether it's timber for bridges or rafts for rangers working the river.
9. Above: After seven hours of bearing loads weighing up to 200 pounds, even the best mules can use a back scratch.
10. Below: At the end of a day that started well before sunrise, Brash takes a break with a good book. "He's smarter than a whip," Bill Workman says. "He may try to make you think he's a dumb hick, but it ain't true. He reads a lot. He can figure out how to build anything just by reading about it in a book."
