Metcalf has conducted work in Colorado, Utah, Idaho, Wyoming, Montana, Kansas, Oklahoma, North and South Dakota, Nebraska, New Mexico, and Texas. Although this service area is large, Metcalf's focus is on the intermountain West, including the Rocky Mountain region north of New Mexico, the Northern and Western Great Plains, and the Eastern Great Basin. This region is characterized by a similarity in prehistoric chronological sequences and the nature of the archaeological sites.

The headquarters of Metcalf Archaeological Consultants, Inc. is located in Eagle, Colorado with offices or workspaces in Denver, Colorado; Cortez, Colorado; and Bismarck, North Dakota.
