He traveled to Oregon Territory via Cape Horn in 1843. He came to the area with a group of men, Charles Eaton, A. M. Poe, Daniel T. Kinsey, A. B. Rabbeson and his partner,
Levi Lathrop Smith. All six men traveled north of the
Columbia River and each took land claims in October 1846. Smith and Sylvester were land claim partners under the partnership clause of the land law of Oregon. They originally named their combined area Smithter or Smithster; it later became Smithfield and eventually became known as
Olympia. In 1848, Levi Smith was the elected delegate to the
Oregon Provisional Legislature. In August of that same year, before he could take up his government position, he had a seizure while canoeing to New Market, capsized and drowned. He was the first recorded American pioneer to die in the area Because of the partnership, Smith's land went to Sylvester and Sylvester abandoned his prairie claim for Smith's claim. He also built the first hotel at this time, which was 16 x 24 feet and roughly built of logs. == Gold rush ==
