2015 Map of Mount Jackson

About this map

Yellowstone National Park defines this section of the Wyoming wilderness, where the Madison River carves its path through Madison Canyon. The landscape is dominated by significant elevations such as Mt Jackson and Mt Haynes, which overlook the western entrance corridor of the park. This 2015 survey illustrates a terrain dictated by hydrology and volcanic geography, with Harlequin Lake tucked into the eastern reaches and the Three Brothers Mountains rising in the southeast. Historical access to this backcountry is marked by the Gneiss Creek Trail and the Cougar Cabin Trail, showing the primitive infrastructure maintained for park management and explorers. The transition between Park County and Teton County is noted in the southern portion of the quadrangle, reflecting the administrative boundaries that intersect this protected natural area.
