Susitna River is on the North side of
Cook Inlet North-East of North Foreland.
Mount Susitna, a prominent landmark along the upper part of the inlet, is about West of the Susitna River at a point above the mouth. The channels across the flats at the mouth of Susitna River have depths of or less at low water and change during the winter and spring because of ice and
freshet action. The channels above the mouth are said to change frequently in the spring and early summer.
Launches navigate Susitna River to
Yentna River, about above
Cook Inlet, thence run occasionally up the
Yentna River to the forks about from the Susitna River. The tides are not felt more than from the inlet, and above this the current is swift. Overhead power cables with a least clearance of cross the Susitna River about above its mouth.
Alexander, Alaska is a small settlement on the west side of Susitna River above the mouth.
Susitna, Alaska is on the East side above the mouth and just below the mouth of the
Yentna River;
launches run to and from
Anchorage, Alaska. Mail is delivered to both settlements twice monthly by airplane from
Anchorage, Alaska.
Susitna Flats lie between big Susitna River and
Little Susitna River and to the East of the latter.
Susitna Flats Light (), above the water, is shown from a
skeleton tower and is equipped with a
racon.
Little Susitna River, West of
Point MacKenzie, is said to be navigable for
landing craft and
skiffs at
high water for about . The depths offshore and in the approach to
Little Susitna River are subject to drastic and continual change. ==Bridges==
