The wind off the Absaroka Range carried the scent of rain and crushed pine, sweeping low across the northern border where Montana gave way to the boundary of Yellowstone.
Colter Vance adjusted his grip on the leather reins, holding his mare steady at the crest of the ridge. To the north lay the wide, open expanses of Paradise Valley—ranch land that his family had worked for three generations, where the Yellowstone River carved a cold, turquoise path through the high country. To the south, marked only by a simple wooden sign post weathered grey by decades of mountain storms, lay the wilderness.
"He's across the line, Colter," Jesse said, pulling his gelding alongside. He pointed down into a steep, timbered draw where the tree canopy broke. "Broke through the boundary fence near the creek. That bull isn't interested in staying on state land."
Colter didn't answer right away. He tipped his hat back, watching a herd of seventy head of cattle scattered across the sagebrush meadow below. Running a ranch on the Montana line meant living on the edge of two very different worlds. On one side was the law of property, brand inspections, and fences. On the other was a million acres of untamed country where no fence held, and where predators and weather wrote their own rules.
"We go down after him, we're in park territory," Jesse added, shifting in his saddle. "Rangers get picky about stock horses in the backcountry without a permit."
"The bull belongs to the ranch, permit or no permit," Colter said quietly. "And if we leave him down in that draw overnight, the grizzly pack up on Electric Peak will have him before dawn."
He nudged the mare forward, descending into the dark shadows of the Douglas firs. The temperature dropped instantly as they crossed beneath the heavy canopy, the soil giving way to damp pine needles that deadened the sound of their horses' hooves. Here, the air felt older, heavier—filled with the subtle, sulfurous tang drifting up from hidden thermal vents miles deeper in the interior.
A mile down the draw, the trees opened into a small clearing centered around a steaming thermal spring. Water bubbled up from a crack in the dark rock, forming a crystal-clear pool fringed with bright green moss. Standing knee-deep in the warm runoff was the runaway bull, entirely unconcerned with property lines or cattle brands.
Colter pulled his rope from the saddle horn, uncoiling the stiff leather loop. "Keep him from bolting into the heavy timber," he told Jesse. "We get him turned around now, or we're spending the night tracking him all the way to Gardiner."
Before Jesse could maneuver his horse, a low snap echoed from the far side of the clearing—the heavy, unmistakable crunch of a large branch breaking under massive weight.
Colter’s mare dropped her ears back, blowing hard through her nostrils as she stepped backward, her muscles tensing beneath the saddle. Across the thermal pool, the brush parted.
