About this map

Colorado River whitewater and high desert topography define this 1985 survey, where the river's winding path creates the prominent horseshoe curve of Big Bend. The map documents a stretch of canyon country rich in natural landmarks, including the northeastern corner of Arches National Park and its famous Delicate Arch. The river corridor is marked by a series of technical water features such as Professor Creek Rapids, New Rapids, and Whites Rapids, indicating the navigational challenges of the era.

Away from the water, the landscape rises into massive geological formations like Dry Mesa and the Dome Plateau. Evidence of human activity is sparse, noted primarily by a Gravel Pit and the named drainages of Professor Creek and Castle Creek. To the east, the Richardson Amphitheater and Parriott Mesa tower over the valley floor, illustrating the dramatic vertical relief of the Castle Valley region.
