Colorado Land Surveyor Practice Exam 2025 – Complete All-in-One Guide to Exam Success

The Colorado Coordinate System consists of two primary zones, the North Zone and the South Zone, used to establish a uniform coordinate framework for surveying throughout the state. The North Zone is designated for the northern part of Colorado, while the South Zone covers the southern areas. The counties included in the North Zone are specifically those situated in the northwestern region of Colorado.

Moffat, Routt, and Jackson counties are located in the northern part of the state and are indeed part of the North Zone. These counties encompass mountainous terrain and are known for their landmarks and geographical features that are vital for proper survey measurements.

In contrast, the other counties listed in the choices fall into the South Zone or do not align with the criteria for the North Zone. Garfield, Eagle, and Summit counties, for example, while generally in the central and western parts of Colorado, do not fit within the North Zone context as they have varying elevations and other geographical considerations that place them in the southern part of the coordinate system. Similarly, Montrose, Ouray, and Hinsdale, and El Paso, Elbert, and Cheyenne counties are situated too far south to be considered part of the North Zone.

Understanding which counties belong to each zone is crucial for land surveying practice
