2011 Map of Poisel Butte

About this map

Poisel Butte rises above the arid drainage patterns of central Washington in this 2011 survey of the Yakama Indian Reservation. The landscape is defined by the ephemeral flow of Mule Dry Creek and Mule Creek, illustrating the seasonal water reliance of this high-plateau region. A network of Bureau of Indian Affairs roads, including BIA 31 Rd and BIA 43 Rd, crisscross the terrain to connect remote outposts and geographic landmarks. Notable for local history and land-use studies is Sampson Cabin in the southeast, a rare named structure in a territory characterized primarily by its natural features and vital water sources like Poisel Butte Spring. The map documents a sparsely settled area where transportation and habitation remain closely tied to the few permanent water features found in the hills.
