The Hanan Trail, a hiking path, runs roughly parallel to the river along this stretch, which is part of the National Wild and Scenic Rivers System. Turning northwest, the Sycan receives Rock, Kelly, and Nixon creeks from the right before turning west again. Over the next stretch, Cummings Creek enters from the right, Rifle Creek from the left, and the Sycan leaves Lake County and enters Klamath County. Skull Creek then enters from the left and Currier Creek from the right.〔 The relevant map quadrangles from mouth to source are Beatty, Spodue Mountain, Riverbed Butte Spring, Sycan Marsh West, Sycan Marsh East, Pole Butte, Riverbed Butte, Shake Butte, Harvey Creek, and Slide Mountain.〕 Downstream of Currier Creek, Paradise Creek enters from the left, and the Sycan turns northwest and then north, leaving Klamath County and re-entering Lake County. Slightly north of the border, Long Creek enters from the right. After turning west and southwest,〔 the river enters Sycan Marsh, a wetland of about .〔(【引用サイトリンク】publisher= The Nature Conservancy )〕 Continuing southwest through the marsh, the river leaves Lake County and re-enters Klamath County. Further downstream, Merritt Creek enters from the left. Meandering west and then south, the Sycan receives Blue Creek from the left, enters Sprague River Valley, receives Snake Creek from the left, and enters the Sprague River north of Beatty.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sycan River」の詳細全文を読む スポンサード リンク
