Limber Pine Outdoors (creators of the White Pine 50) is excited to announce a NEW hundred-miler connecting the iconic elkhorn arches located in Afton and Jackson Hole Wyoming! Each winter, thousands of elk, the “Monarchs of the Mountains” travel a hundred miles or more to descend out of the nearby mountain ranges to elk feeding grounds in Star Valley and Jackson Hole. In the spring, the bulls drop their antlers before returning to their lofty haunts high above the valley floor. Both towns have erected massive arches made from these elk “sheds” in honor of this annual feat of biology. If you qualify (keep reading), we invite you to make the journey yourself through the terrain these elk navigate between their summer and winter ranges and back.
