Twentymile River
The Twentymile River is a river near the Kenai Peninsula in Alaska. It rises in a remote valley from meltwater of several small glaciers in the Chugach Mountains and flows out into a large, wide valley where it receives the water of the Moraine and Glacier rivers. Eventually, the river empties into Turnagain Arm after flowing to a broad marshy delta alongside the deltas of Portage Creek Portage Creek is a census-designated place (CDP) in Dillingham Census Area, Alaska, United States.

Seward Highway
The Seward Highway is a highway in the U.S. state of Alaska that extends from Seward to Anchorage. It was completed in 1951 and runs through the scenic Kenai Peninsula, Chugach National Forest, Turnagain Arm, and Kenai Mountains. The Seward Highway is numbered Alaska Route 9 (AK-9) for the first from Seward to the Sterling Highway and AK-1 for the remaining distance to Anchorage. At the junction with the Sterling Highway, AK-1 turns west towards Sterling and Homer. About of the Seward Highway leading into Anchorage is built to freeway standards. In Anchorage, the Seward Highway terminates at an intersection with 5th Avenue, which AK-1 is routed to, and which then leads to the Glenn Highway freeway. Route description The full length of the Seward Highway has been listed on the National Highway System (NHS), a network of roads important to the country's economy, defense, and mobility.

Portage Peak
Portage Peak is a elevation mountain summit located in the Chugach Mountains, in Anchorage Municipality in the U.S. state of Alaska. The peak is situated in Chugach National Forest, immediately east of Twentymile River valley, and west of Begich Peak. It is set midway between Girdwood and Whittier, with the Portage Glacier Highway and Alaska Railroad traversing the southern base of the mountain. Precipitation runoff from the peak drains into Turnagain Arm via Portage Creek and Twentymile River. This mountain is unofficially named in association with the creek and nearby Portage Lake, Portage Glacier, and Portage ghost town. Climate Based on the Köppen climate classification, Portage Peak is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. Weather systems coming off the Gulf of Alaska are forced upwards by the Chugach Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Temperatures can dr ...

Portage, Anchorage
Portage is a ghost town and former settlement on Turnagain Arm in Alaska, about southeast of Downtown Anchorage. The town was destroyed in the 1964 Alaska earthquake when the ground in the area sank about , putting most of the town below high tide level. All that remains today are the ruins of a few buildings and a " ghost forest" of trees that died after salt water inundated their root systems. Where there was once a town there is now only a railroad and road junction linking the Seward Highway and the Alaska Railroad to Portage Glacier park and the Anton Anderson Memorial Tunnel, which leads to Whittier.The Milepost, 59th edition, page 540 Popular recreational activities in the Portage area include visiting the wildlife center, floating Portage, Twentymile, Placer rivers, fishing for hooligan in the Twentymile river, and ice skating the numerous marshy areas, creeks, and Portage Lake.

River Mouth
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.

Turnagain Arm
Turnagain Arm ( Dena'ina: ''Tutl'uh'') is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches at the north end of Cook Inlet, the other being Knik Arm. Turnagain is subject to climate extremes and large tide ranges. Geography Turnagain extends in an east-west direction, and is between long. It forms part of the northern boundary of Kenai Peninsula, and reaches on the east to within of Passage Canal, a western branch of Prince William Sound. Turnagain is characterized by remarkably large tides of up to 40 feet (12 meters) which are the largest tides in the United States. The flood tide often begins with a tidal bore especially on large tides with a strong east wind, which has a height of at times, and runs in from the west at a speed of an hour. At low tide, the arm becomes a broad mud flat, cut by the stream channels. Historically small steamers entered and left on high water though the practice is rare at best since most if not all the ...

Moraine River
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Proven ...

Kenai Peninsula
The Kenai Peninsula ( Dena'ina: ''Yaghenen'') is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai (, ) is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe, the Kahtnuht’ana Dena’ina ("People along the Kahtnu (Kenai River)"), who historically inhabited the area. They called the Kenai Peninsula ''Yaghanen'' ("the good land"). Geography The peninsula extends about southwest from the Chugach Mountains, south of Anchorage. It is separated from the mainland on the west by Cook Inlet and on the east by Prince William Sound. Most of the peninsula is part of the Kenai Peninsula Borough. Athabaskan and Alutiiq Native groups lived on the peninsula for thousands of years prior to Gerasim Izmailov becoming the first European to explore and map the area in 1789. The glacier-covered Kenai Mountains, rising , run along the southeast spine of the peninsula along the coast of the Gulf of Alaska. Much ...

Chugach Mountains
The Chugach Mountains of southern Alaska are the northernmost of the several mountain ranges that make up the Pacific Coast Ranges of the western edge of North America. The range is about long and wide, and extends from the Knik and Turnagain Arms of the Cook Inlet on the west to Bering Glacier, Tana Glacier, and the Tana River on the east. It is bounded on the north by the Matanuska, Copper, and Chitina rivers. The highest point of the Chugach Mountains is Mount Marcus Baker, at , but with an average elevation of , most of its summits are not especially high. Even so, its position along the Gulf of Alaska ensures more snowfall in the Chugach than anywhere else in the world, an annual average of over 1500 cm (800 in).Steep, Freeskiing Documentary, 2007 The mountains are protected in the Chugach State Park and the Chugach National Forest. Near to Anchorage, they are a popular destination for outdoor activities. The Richardson Highway, Seward Highway, Portage G ...
