Iditarod National Historic Trail I Historic Overview — Robert King
Iditarod National Historic Trail i Historic Overview — Robert King Introduction: Today’s Iditarod Trail, a symbol of frontier travel and once an important artery of Alaska’s winter commerce, served a string of mining camps, trading posts, and other settlements founded between 1880 and 1920, during Alaska’s Gold Rush Era. Alaska’s gold rushes were an extension of the American mining frontier that dates from colonial America and moved west to California with the gold discovery there in 1848. In each new territory, gold strikes had caused a surge in population, the establishment of a territorial government, and the development of a transportation system linking the goldfields with the rest of the nation. Alaska, too, followed through these same general stages. With the increase in gold production particularly in the later 1890s and early 1900s, the non-Native population boomed from 430 people in 1880 to some 36,400 in 1910. In 1912, President Taft signed the act creating the Territory of Alaska. At that time, the region’s 1 Iditarod National Historic Trail: Historic Overview transportation systems included a mixture of steamship and steamboat lines, railroads, wagon roads, and various cross-country trail including ones designed principally for winter time dogsled travel. Of the latter, the longest ran from Seward to Nome, and came to be called the Iditarod Trail. The Iditarod Trail today: The Iditarod trail, first commonly referred to as the Seward to Nome trail, was developed starting in 1908 in response to gold rush era needs. While marked off by an official government survey, in many places it followed preexisting Native trails of the Tanaina and Ingalik Indians in the Interior of Alaska. -

National Trails System Act
Connecting Trails Across the Nation . National scenic trails are 100 miles or longer, continuous, primarily non- motorized routes of outstanding recreation opportunity. Such trails are established by Act of Congress. National historic trails commemorate historic (and prehistoric) routes of travel that are of significance to the entire Nation. They must meet all three criteria listed in Section 5(b)(11) of the National Trails System Act. Such trails are established by Act of Congress. National recreation trails, also authorized in the National Trails System Act, are existing regional and local trails recognized by either the Secretary of Agriculture or the Secretary of the Interior upon application.

Arizona Trail . Florida Trail . Natchez Trace National Scenic Trail . New England National Scenic Trail . North Country National Scenic Trail . Pacific Northwest National Scenic Trail . Potomac Heritage National Scenic Trail . The Appalachian Trail is a 2,180+ mile long public footpath that traverses the scenic, wooded, wild, and culturally resonant lands of the Appalachian Mountains. Conceived in 1921, built by private citizens, and completed in 1937, today the trail is managed by the National Park Service, US Forest Service, Appalachian Trail Conservancy, numerous state agencies and thousands of volunteers. The Appalachian Trail spans from Maine to Georgia (through 14 different states), with the highest point being Clingman’s Dome in Tennessee. Less than 15,000 people have successfully thru hiked the trail. *Sources: National Park Service Website . The Ice Age National Scenic Trail is a thousand- mile footpath that highlights these landscape features as it travels through some of the state’s most beautiful natural areas. -

The History of the Iditarod Trail Sled Dog Race® Since 1973, Mushers
The History of the Iditarod Trail Sled Dog Race® Since 1973, mushers have challenged themselves in a race nicknamed The Last Great Race on Earth®, racing each March from Anchorage to Nome, Alaska. Nearly a thousand miles in length, mushers and teams travel over mountain ranges, through monotonous, flat tundra, to the western Alaskan coast and finally to the town of Nome, established when gold was discovered there in 1898. By 1899, Nome's population numbered 10,000. The route that most of the race follows is a trail that was created long before the race became a race. Used by Native Alaskans for hunting and travel to various villages, the Iditarod Trail was cleared in 1908 by government employees, but it wasn't until the 1910 gold discoveries in Iditarod which is a ghost town now, Ruby, Ophir, Flat, Nome, Elim, and other villages, that it became regularly used as a means of supplying miners and settlements with mail and supplies, delivered by dog team. It also provided the route for gold to be sent out of Alaska when the Bering Sea was frozen, preventing ships from reaching Nome for months at a time. Dog sled teams carried gold to the ice-free bay at Seward to be loaded on ships there. Before the time of airplanes delivering mail and supplies to remote Alaskan areas, dog teams did the job. Alaskan Natives had been using dog teams in their way of life, a subsistence lifestyle which depended upon hunting, fishing, and gathering to provide food. Dog teams helped them travel, carry game they hunted, and carry food and water. -

Ecosystem-Based Chinook Salmon, Oncorhynchus
Ecosystem-based Chinook Salmon Oncorhynchus tshawytscha Management Plan of the Susitna River Drainage Authors: William Middleton (primary contact), Allison Thomason, Ashley Williams, Abraham Meyer, David Pomelow Coach: Roger R. Saft, Ph.D. Assistant Coach: Wendy Garrett [email protected] Aurelia Wasilla High School 701 East Bogard Road Wasilla, Alaska 99654 Abstract The fishery is Susitna River chinook salmon (Oncorhynchus tshawytscha) fishery on the Northern Cook Inlet. It is the largest in size of all Pacific salmon species. Management of the fish, like any other natural resource in the state of Alaska, is controlled by the Alaska constitution. The requirement is to manage to achieve maximum benefit to the citizens of the state and to preserve the species by establishing and maintaining maximum sustained yield. Present to a lesser extent in the Susitna River drainage is the coho salmon (Oncorhynchus kisutch). Sockeye salmon (Oncorhynchus nerka) are a major contributor to the fisheries of the Upper Cook Inlet and the Susitna River system tributaries. Burbot (Lota lota) are a fish species present not of commercial significance. Present also in the Susitna River basin is the rainbow trout (Oncorhynchus mykiss). It is not managed for commercial harvest. Also inhabiting the drainage without commercial significance are Arctic grayling (Thymallus arcticus). The Susitna River chinook salmon fishery is one of the largest fisheries in Alaska and provides much of the world with salmon. It brings a large amount of revenue for the state and its citizens. Because of the large amount of fish and for the enjoyment, many sport fishermen go out and by fishing supplies and licenses so as to ensure that they catch a trophy fish. -
