Classes of Inventory in Wyoming

Class I: Existing Data Inventory

A Class I inventory is a compilation and analysis of existing cultural resource data and a management-focused, interpretive narrative overview and synthesis of the data. It includes, but is not limited to, a file search of the Wyoming SHPO Cultural Records Office database.

Class II: Sampling Field Inventory

A Class II inventory provides the database for making an objective estimate of the nature and distribution of cultural resource sites within a study area. Field investigations usually include transects of greater than 30 meters (100 feet). A sampling strategy must be justified with a written proposal, and reviewed and accepted by all reviewing agencies in advance of the inventory.

Class III: Intensive Field Inventory

A Class III Inventory provides cultural resource specialists and managers with a record of all cultural properties, which can be identified from surface indications, for a specific area. Thirty meter (100 feet) transect spacing (at a maximum) is required for a Class III inventory.

Reconnaissance Inventory

A reconnaissance inventory is a focused or special-purpose information tool that is less systematic, less intensive, less complete, and otherwise does not meet Class III inventory standards.
