[1] Its course takes it past Lemon Creek Correctional Center and passes under a bridge built along Juneau's arterial Glacier Highway before emptying on the tidal flat at the head of Gastineau Channel, 5 miles (8.0 km) northwest of the borough of Juneau.
From the south, there are several good-sized tributaries, and the uppermost of these side valleys contains a large glacier, which merges with the ice from the head of the main valley and extends to a point only 6 miles (9.7 km) from the mouth of the creek.
The stream bed lies north of the central line of the valley, and on this side the tributaries are closely spaced and their channels only slightly incised in the mountain flank.
The mouth of the valley is filled by a delta deposit raised only a few feet above high tide and extending upstream for something over a mile.
Then comes a cascade, giving a rise of several hundred feet in a distance of half a mile, and above this the grade is somewhat more gentle, and short gravelly flats occur from place to place, separated by reaches of steeper slope extending to the foot of the glacier.
