Hype for the Future 142B: State of Alaska Explained

Introduction The State of Alaska is uniquely located largely, though not entirely, north of the Arctic Circle at the northwestern edge of North America, famously ending with the Alaskan Panhandle extending well to the south of the Arctic—as far south as approximately 54°40’ North. However, the Aleutian Islands of the State of Alaska also extend even further south than the Alaska Panhandle, with the southernmost island, Amatignak, near 51° North. Communities Within the State of […]

“... Several things stand out:
1) the massive flow of the mighty Mississippi and Columbia River systems
2) the paucity of major rivers in the western US, especially the southwestern US, where the only major rivers are the seriously over-tapped Colorado and Rio Grande Rivers
3) the local importance of the Sacramento-San Joaquin Rivers in California, which serve the state’s cities and agricultural regions…”
