About this map

Wrangell-Saint Elias National Preserve encompasses the high-altitude terrain shown in this 2016 survey of the Wrangell Mountains. The landscape is defined by its drainage network, with Jacksina Creek flowing northward through the central valley, joined by tributaries like Tumble Creek and Mesa Cr. A notable alpine water body, Grizzly Lake, sits at an elevation of approximately 4,200 feet, surrounded by steep contour lines that illustrate the sharp vertical relief of the region.

The map details a portion of the Copper River Basin's eastern reaches during the mid-2010s. The absence of roads or permanent structures underscores the wilderness character of the preserve, emphasizing instead the natural hydrography and topographical features that have shaped this part of Alaska for centuries. For those studying the hydrology of the northern Wrangells, the precise mapping of creek headwaters and the glacial terrain around the lake provides valuable data on the area's physical geography.
