Representing the US in Numbers   

The 1870 Census documented the momentous changes ushered in by the Civil War. Maps, charts, and reports conveyed information about the consolidation of the nation—including new states and territories, a transcontinental railroad, and mining surveys.   

Also embedded in the census were hints of unease regarding race, religion, and claims to rule. This map showed that while most Americans still lived east of the Mississippi, Native peoples were increasingly confined to Indian reservations in the West. In the next few decades, the US would pursue military, political, legal, and educational measures to further control Native lands and lives.

Representing the US in Art   

After the Civil War, Congress funded multiple scientific surveys of western lands. Each survey generated reams of data pertinent to the nation's economic development. But it was the artistic products—created by photographers and artists who accompanied the expeditions—that publicized the West for a national audience.   

While surveying Colorado in 1873, photographer William Henry Jackson captured the first documentary image of this 14,000-foot mountain in the Rockies. Its distinctive cross-shaped snowfield had been spoken of as a Christian symbol since the time of Spanish exploration, but few had seen it. Jackson's photograph made the Mountain of the Holy Cross a familiar icon.  

Jackson’s photograph also inspired the western landscape painter Thomas Moran to travel to Colorado to create his own version of this natural wonder. Moran's monumental painting went on display in Washington, DC, in 1875, where it would have reinforced the prevailing idea of a divinely sanctioned westward expansion.
