Goodale's Cutoff formed a spur of the Oregon Trail beginning in Idaho, United States. The cutoff left the trail near Fort Hall, crossed the Snake River Plain to the Lost River, and then turned west to the area of Boise, crossing Camas Prairie. It rejoined the main trail from Ditto Creek to Boise, then ran to the north of the main trail, crossing the Snake River into Oregon at Brownlee's Ferry. In Oregon travelers could now reach the Eagle Valley and Pine Valley areas, and the gold mines in Auburn. The cutoff rejoined the main Oregon Trail at the Powder River, near Baker City.
