1964 Map of Henrieville

A network of rugged paths and specialized routes, such as the Jeep Trail and the road through Kodachrome Flat, illustrates the area's isolation and its reliance on durable transportation for land management. To the south, the county line between Garfield and Kane Counties bisects a region characterized by deep depressions like Big Dry Valley and distinctive geological markers such as Chimney Rock. This period of the survey reflects a landscape still largely primitive in its infrastructure, primarily utilized for grazing and mineral exploration, as evidenced by various prospects and a drill hole.
