Prehistoric refers to information about people and events prior to the advent of writing. The period of prehistory differs around the world depending upon when written records became common in a region. Current evidence confirms that people were established in northern Wyoming beginning about 12,000 years ago, however some evidence suggests that human occupation of this area may have occurred significantly earlier.
History is the study of past events and times through the use of written and recorded sources, as well as oral sources. Historic in this context refers to the period after Europeans arrived in the North America.
The potential effect on cultural resources from any proposed land use activity that requires a decision or authorization by the Cody Field Manager, involves federal funds or requires a BLM permit, must be taken into consideration during BLM's decision-making process. A variety of laws, regulations, Executive Orders and governmental policy and directives govern this process.
