http://en.wikipedia.org/wiki/Timeline_of_the_Lewis_and_Clark_Expedition\n\nThe closest I can get is Nov 7, 1805.  No electric headlights or alarm clocks back then, so they would have to get up with the sun, get dressed and ready in the miserable Oregon winter weather (cold rain), pack up their entire encampment like a circus, trot down to their canoes, and start paddling and portaging.  I'm guessing noon at the earliest, with 4:00PM at the latest (they'd need to stop before sunset so that they could set up their camp before the daylight ran out).

Most goes strait back to the Pacific Ocean.  The rest goes east to the Puget Sound and north to the Strait of Juan de Fuca, and then to the Pacific after that.

They got there the same way they got to all the other Pacific islands.  They used boats.\n\nThe ancient Polynesians were excellent navigators.  They used things like the currents, the presence of fish and seaweed, and subtle wave patterns that reflect off of nearby islands to help them find their way around.  It is really quite amazing.

the answers given are correct, minor exception that the line crosses the aleutian island chain thus making Alaska the most East and Western state of the US. \n\nFun note...flying in a plane across the Pacific, the pilot will usually announce when they are crossing the Date Line.  Take note on how many people look out the window to see it.

Pacific Islanders sailed to and settled islands all over the Pacific without Google, GPS, compasses, sextants, the concepts of latitude and longitude, or even paper maps.\n\nThey could do it because they knew a great deal about the stars, the ocean, the fish, the birds, and the earth in general. A traditional Pacific navigator like Mau Pialug of Satawal in Micronesia is always feeling the pattern of the ocean waves against the side of the canoe, knows where the stars are even when it's cloudy, can see the position of Tahiti in his mind's eye, even when it's thousands of miles away, and all the eye can see is open ocean. \n\nSince the 1970s, modern Pacific Islanders have proven again and again that they can sail thousands of miles on replicas of traditional voyaging canoes using only these navigational techniques. The replica Hokule'a (Star of Gladness) has sailed to Tahiti several times from Hawaii, to New Zealand, to Rapa Nui (Easter Island), to Samoa, to Alaska, and many other places. \n\nThe first link below takes you to a page with many links on the left with information about traditional navigation methods. You should explore the links on the top as well--lots of fascinating information.\n\nThe second link brings you to a bookstore with several books on the topic. I recommend Finney's Sailing in the Wake of the Ancestors.\n\nThe third link has ordering information for the PBS documentary "Wayfinders: A Pacific Odyssey". I highly recommend that one, and not just because an old classmate of mine is featured as a navigator in training! \n\nThe fourth link is to an article that features Micronesian Stick Charts, what navigators in places like the Marshall Islands used for maps. \n\nLots to explore here. It's a big ocean!

Coz the water comes from the Pacific and goes into the Atlantic

It was a land bridge over the Bering straits, they traveled down the west coast and spread out from there.\nGreat Question, there is also speculation some Egyptians, sailed to the east coast, we have even seen signs of people from king Davids reign settled in the south, New Mexico.

Somewhere in the Pacific Ocean.

Correct ... there were already lots of people in North America when Columbus got here, including the Inuit who probably crossed the Bering Sea from Asia on the ice bridge thousands of years before Columbus.

Iceboating is mentioned in "Around the World in Eighty Days" when Phileas Fogg and his travelling companions have to cross from Chicago to New York when the trains are snowed in. The book was published in 1872.

The Ancient Times:\n-The first settlers were migrating Polynesians, who navigated the Pacific in voyaging canoes, believed to have first arrived from the Marquesas Islands with subsequent migrations from Tahiti, and perhaps other Pacific islands.  \n-nearly all of the habitable islands in the Pacific Ocean were settled hundreds of years before European sailors dared venture beyond the site of land \n-By the time of Cook's arrival in 1778, the population of Hawai`i had grown to something between 400,000 and 800,000 people, perhaps more.  It was a stone age society since there are no metals found in the islands, however this term might give a false impression that the society was primitive.  Hardly!  Some have estimated that the population of the islands, based on the methods of food production and the living conditions, could have exceeded one million and even approach current day population of 1.2 million\n\nThe Monarchy Years:\n- begins with the unification of the islands by Kamehameha the Great in 1810, shortly after the arrival of Captain Cook, until the overthrow of the Hawaiian government in 1893. During this relatively short period of time, the people of Hawai'i would transition from a feudal society into an independent constitutional monarchy, recognized by other nations around the world.  \n-Two years after the Declaration of Independence, and while the American colonies were still fighting to be independent, Captain James Cook arrived in Hawaii. At the time, Hawaii was in the process of moving from regional monarchs, usually one per island, to a consolidated monarchy that spanned all the islands.\n-Kamehameha I (the Great) of the Island of Hawaii first consolidated his power there. He then conquered Maui and Oahu.Kamehameha then attempted to invade Kauai, but his fleet was turned back by a storm. Following several years, the ruler of Kauai decided to pledge his allegiance to Kamehameha, and the unification of the Hawaiian islands was complete.\n-Hawaii in 1778 in many ways resembled feudal Europe. The major difference, other than religion, was the absence of writing and metal. Hawaii was isolated and had no continuous contact with other civilizations. \n-What took hundreds of years to evolve in Europe, happened virtually overnight in Hawaii. American missionaries arriving in 1820 brought with them not only their religion, but their political and social views. \n-The missionaries taught reading and writing, and the Hawaiians overwhelmingly responded - many say they achieved a higher rate of literacy than that in the United States at the time. By 1840, a mere 62 years after the first European contact, Kamehameha III promulgated the first Hawaiian Constitution. Just as the Magna Charta subjected King John of England to the rule of law, the 1840 Constitution subjected Kamehameha and his heirs to the law. The 1840 Constitution established a House of Nobles and an elected House of Representatives whose assent to new laws and changes to the Constitution was required. In less than a generation Hawaii went from a hereditary despotic government based on divine right to a Constitutional monarchy with an elected legislature.\n-Subsequent Constitutions were adopted in 1852, 1864 and 1887 (the bayonet Constitution). Hawaiian Constitutional history can be viewed as decreasing the powers of the Crown, and increasing those of the people through their elected representatives.\n-The precipitating event for the overthrow of the Monarchy and Queen Lili'uokalani was her proposed new Constitution. Among other things, Queen Lili'uokalani's Constitution would have restored to her the power to appoint the House of Nobles, and to veto Constitutional amendments. \n\nTerritorial Years: 1898 - 1959\n  \n-The Territory of Hawaii was created on July 7, 1898, when Congress passed the Newlands Resolution annexing Hawai'i to the United States. The formal ceremony took place in Honolulu on August 12, 1898. The Newlands Resolution

In the southern half of the ocean the Humboldt Current flows north along the coast of South America. The cold mineral rich waters support many millions of small fish, which are eaten by larger fish and seabirds.\nAt regular intervals a huge area of the Pacific becomes warmer. Because warm water rises above cold, the sea-level increases. This change in temperature and level causes an alteration in the pattern of the winds. The warm water travels across the Pacific at 100 kms a day. This phenomenon, known as El Nino, deflects the Humboldt Current. 1997 saw the highest temperature recorded of this warm water during the last 150 years.
