Horse Creek begins in which North American mountain range?
Horse Creek (McKenzie River) Horse Creek is a tributary of the McKenzie River in near the unincorporated community of McKenzie Bridge in Lane County in the U.S. state of Oregon. It begins in the Cascade Range in the Three Sisters Wilderness of the Willamette National Forest. Its headwaters are near the Deschutes County border and the Pacific Crest Trail. It flows generally northwest to meet the river about 65 mi upstream of the McKenzie's confluence with the Willamette River.
Clear Creek (Colorado) Clear Creek is a tributary of the South Platte River, approximately 66 mi long, in north central Colorado in the United States. The creek flows through Clear Creek Canyon in the Rocky Mountains directly west of Denver, descending through a long gorge to emerge on the Colorado Eastern Plains where it joins the South Platte. Clear Creek is unusual in that it is a stream named "creek" fed by a stream named "river". Fall River empties into Clear Creek along I-70 west of Idaho Springs, Colorado.
