What does a man want? Adventures—titanic adventures. A gargantuan land, bristling with mountains and swelling with rivers. A woman to share his fire and his buffalo robes. Children to learn and live beyond. A living, maybe an empire, to leave to them. Mac Maclean wanted all that and more. He came ahead of the emigrants to the valley of the Yellowstone River, he and a handful of other white men, venturers deep into Indian territory, companions of Indians, friends of Indians, husbands and fathers to Indians. He hunted, he traded, he battled, he wed and bred—he gave his all for the life that made his heart pump hard. He lives still in the Yellowstone country, as legend.
