In the footsteps of Mountain Men, the Teton adventure awaits

In 1847, the legendary trapper Jean-Baptiste Gervais vanished into the Jackson Hole wilderness with a fortune in beaver pelts and a coded journal. For nearly 180 years, his cache remained hidden—until fragments of his cipher surfaced in the town's oldest buildings. Local historians believe the key to finding Gervais's treasure lies scattered across eight historic sites in Jackson's downtown core: the saloons where fur traders once haggled, the trading posts that supplied expeditions, and the graves of mountain men who knew his secrets. You have one evening to piece together the cryptic symbols, decode the trapper's route, and uncover where Gervais buried his wealth before a rival expedition arrives at dawn. Every landmark holds a clue; every riddle brings you closer to the truth—and to fortune.

« A region of savage sublimity. »
Washington Irving, Astoria (1836), describing the Rocky Mountains.

The Fur Trapper Era and the Tetons

The Jackson Hole valley, nestled at the foot of the imposing Tetons, was discovered by American explorers in the early 19th century. The first Westerner to set foot there was John Colter in 1807-1808, a former member of the Lewis and Clark expedition, who traversed the region during his solitary exploration. The valley quickly became a hub for the fur trade, attracting "mountain men" like David Jackson, who gave his name to the area in 1829. These trappers, iconic figures of the American West, spent months, even years, in the solitude of the mountains, hunting beaver and trading their furs at large annual rendezvous.

These rugged and independent men blazed the first trails and established the first camps in a hostile yet magnificent environment. Their stories, often unwritten, are filled with adventures, discoveries, and survival against wild nature and indigenous tribes. The heyday of the fur trade ended around the 1840s, as beaver became scarce and silk hats replaced beaver felt hats. However, the legacy of these pioneers endures, embodied by place names, the trails they trod, and the untamed spirit that continues to define Wyoming.
