Archeological evidence suggests that Native Americans lived along the lower Columbia River as early as 10,000 years ago. The area near what later became The Dalles, on the Columbia east of the mouth of the Sandy River, eventually became an important trading center. The Indians established villages on floodplains and traveled seasonally to gather huckleberries and other food on upland meadows, to fish for salmon, and to hunt elk and deer. Although no direct evidence exists that these lower-Columbia Indians traveled up the Sandy, it is likely that they did. Traces of these people include petroglyphs carved into the rocks of the Columbia River Gorge. Within the past few thousand years, Indians created trails across the Cascade Range around Mount Hood. In the 19th century, this trail network linked the Wascopam Mission near The Dalles to settlements in the Willamette Valley. One popular trail crossed over Lolo Pass, near the headwaters of the Bull Run River, and another, which later became the Barlow Road, met the Lolo Pass trail roughly where the Zigzag and Salmon rivers enter the Sandy. Indians from villages along the Columbia, Clackamas, and other rivers also traveled by water to the lower Sandy River area to fish for salmon and to gather berries, nuts and roots. The Klickitat tribe referred to Bull Run Lake as Gohabedikt, meaning Loon Lake.
