  1. The Northern Lights And the Lakes of the Yukon Territory Lake Tagish Lake Laberge Lake Bennett

  2. Locations of the Three Lakes • The three most important lakes in the Yukon Territory are Lake Tagish, Lake LeBerge, and Lake Bennett. • Lake Tagish- 30 minutes from Whitehorse • Lake LeBerge- 55 miles from Whitehorse • Lake Bennett- 35 miles from Dyea

  3. Size of the Lakes These large lakes spread across vast areas of the Yukon • Lake Tagish- originates in the Yukon River and spreads over km • Lake Leberge- was formed by glacial activity in the Ice Age, making it 14 to 54 miles in depth • Lake Bennett- only 1 mile, but has many treacherous rapids and rocks

  4. Uses for the lakes water resources during Gold Rush Lake Bennett- charter passages, special occasions, transportation routes, camping and fishing during spring and summer Lake Tagish- a settling place for stampeders also during Gold Rush

  5. While prospectors used the three rivers, The Northern Lights always glowed above.

  6. Location Found between 60-620 miles above earth Can extend thousands of miles across the sky Common closer towards the North Pole (Alaska, Greenland, etc.) but have been seen as far away as Mexico Nicknamed Northern Lights because of its presence in only the Northern Hemisphere

  7. Colors of Northern Lights The altitude and atoms determines the colors you see. Blue, violet, and red= less than 60 miles above earth Bright green=60-150 miles above earth Dark red= above Usually yellow or green Nitrogen atoms create blues, violets, and reds Oxygen atoms create greens and other reds

  8. Movements Movements of the Northern Lights differ, but can be seen as: Currents Lively colors Unfazing glows And countless other actions

  9. Sounds There have always been people who claim to hear the Northern Lights Heard as crackling, rustling, and whooshing sounds No theory has yet confirmed, disconfirmed, or proved this to be true or not Some people do not believe they exist

  10. What exactly are the Northern Lights? Energy from the sun flows away in electrified particles, called plasma, because of uncontrollable weather Solar wind, plasma from the sun, comes in contact with earth, but is directed to the North and South Poles because of our protective magnetic shield After being trapped in magnetic belts, it arrives to the poles and a large discharge of solar wind collides with the magnetic field

  11. What exactly are the Northern Lights? • While colliding in the atmosphere, ions or atoms are energized and are altered by the lines of the magnetic force • the energy inside of them increases and the atoms or ions collide with oxygen and nitrogen atoms to create colors • The magnetic field is squeezed because of the pressure, and lines of the field disconnect and reconnect which lets solar wind slip through to the poles
