Snow River, Brook in Kenai Peninsula, US

The Snow River is a 28-mile (45 km) tributary of Kenai Lake, rising at the foot of the Snow Glacier in the Kenai Mountains and flowing southwest through the Paradise Valley in Chugach National Forest. Below its junction with the 20 km South Fork Snow River, the Alaska Railroad crosses it, and the Seward Highway crosses just before its mouth at the lake's southern inlet.

The river's lower course is followed by the Seward Highway (Alaska Route 9) on its west bank, and the Alaska Railroad line between Seward and Anchorage crosses the Snow River just below the confluence with the South Fork. The Iditarod Trail also intersects the river along its final reaches near Primrose, at the southern inlet of Kenai Lake.

The river's name is a direct English rendering of the Dena'ina and Russian-era usage recorded for the waterway, and the South Fork Snow River, 20 km long, rises at 970 m west of Nellie Juan Lake. The lower river passes the Iditarod Trail and the Seward Highway crossing near its mouth, routes that carry travellers along the Kenai Peninsula today.

The Seward Highway (Alaska Route 9) runs along the west bank of the lower river and crosses the Snow River just before its mouth at the south end of Kenai Lake. The Alaska Railroad line between Seward and Anchorage crosses the river below the confluence with the South Fork. The river also meets the Iditarod Trail in its final reaches.

The glacier feeding the Snow River holds back a lake that empties every few years, sending floodwater into Primrose and Kenai Lake. The river's lower reach also crosses the Iditarod Trail and passes beneath the Seward Highway just before its mouth.
