2019 Map of Ruby C-1 SW

USGS Topo · Published 2019

About this map

The Big Mud River meanders across the southern reaches of this interior Alaska landscape, defining the low-lying drainage patterns of the T11s R27e and T11s R28e townships. This 2019 survey documents a vast, undeveloped expanse where the terrain rises sharply from the river basin into a series of high ridges and narrow valleys. To the north, the headwaters of Grand Cr carve through the uplands of T10s R27e, illustrating the complex topography of the Yukon-Koyukuk region. The absence of roads or permanent structures on this sheet underscores the preservation of a wilderness character nearly unchanged by modern infrastructure. Researchers can trace the natural hydrology of the river’s oxbows and the steep contour gradients that define the divide between these two primary water systems.
