Sunlight Creek

In the early 1800s, prospectors and fur traders trapped in dense fog in the mountains named the Sunlight Basin after the sudden sunlight-covered valley. According to them, "the only thing that can get into this valley most of the year, is sunlight."^[3] Sunlight Creek, which flows east through the middle of the area from the mountains into the canyon, is named for the basin.

In 1877, Chief Joseph and his Nez Perce travelled through Sunlight Gorge whilst escaping US cavalries,^[3] as part of three months and 1,170 miles (1,880 km) outmaneuvering them through present-day Oregon, Washington, Idaho, Wyoming, and Montana during the Nez Perce War.^[4]

On November 20, 2018, work began on a project by the Wyoming Game and Fish Department to prevent erosion of Sunlight Creek, which threatened the area inhabited by moose and elk, the bridges that cross the creek, power lines in the area, and local fishing, by rechanneling the creek.^[5]

In 1985, the Sunlight Creek Bridge was built across the Sunlight Gorge, carrying Chief Joseph Scenic Byway (Wyoming Highway 296) and two pedestrian walkways.^[6] At 285.4 ft (87.0 m), it is the highest bridge in Wyoming.^[7]

Sunlight Creek is followed and crossed by a gravel road, Sunlight Road (Forest Road 101), for the majority of its course, which provides access to campgrounds along the river in the North Absaroka Wilderness area,^[8] as well as other off-roading trails and forest roads.
