Here is another photo of Juneau taken after nightfall from atop Mt. Roberts. The lights in the foreground represent Juneau's downtown area. The lights in the background are about 9 miles away and comprise of the airport and surrounding neighborhoods. The furthest islands visible are in Auke Bay which is about 12 miles from downtown. The waterway down the middle is the Gastineau Channel which separates the mainland from Douglas Island. There is only one bridge across and the channel is only navigatable beyond the bridge by small boats at high tide.
