2018 Map of Mount Michelson C-1 NW

About this map

Sadlerochit Mountains dominate the southern portion of this Arctic landscape, where steep topography transitions into a broad coastal plain to the north. The drainage network is defined by the Sadlerochit River, which flows through the Sadlerochit Valley alongside several seasonal and perennial watercourses. An interesting hydrological feature is the Sadlerochit Spring, situated at the base of the mountains where groundwater likely emerges to feed the local river system. To the northwest, Itkilyariak Creek carves a path through the low-lying tundra, while the smaller Last Cr joins the larger river system in the southern mountain foothills. This 2018 survey illustrates a remote corner of the North Slope where the hydrology is intrinsically linked to the underlying mountain geology.
