A plain speaker for plain folks, Lincoln blended his love of the written word with a strong work ethic and pursued a legal career, then a political one from the Illinois state legislature to the U.S. Congress. Here was a man who aspired to lead a nation.

300 BCE - 700 CE, The Basketmakers of Sivu'ovi at Petrified Forest National Park - The Arizona Petrified Forest National Park contains one of the world's largest concentrations of petrified wood, historic structures, archaeological sites and fossils. Scattered throughout the park are traces of nearly 13,000 years of human history and culture. Located in the southern portion of the Petrified Forest National Park, Sivu'ovi is an extensive site containing the remains of a large Basketmaker II period pit house village and several small Pueblo period rubble mounds. The Basketmaker II period is the least studied period of occupation in the region. Many of the structures are situated on the edge of the bluff, which faces serious erosion problems. Theft of petrified wood is also an ongoing problem at the park, and nearly 14 tons of the fossil wood disappear from the forest each year.

This specific capsule is on exhibit in the Chabot Space Center in Oakland, California. CyArk received the laser scans in 2004 from the Space Center to provide a digital record of this important part of astronautical history.
