About this map

Alberton and the smaller settlement of Lothrop occupy the northern corridor of this landscape, situated along the Clark Fork river at the boundary of Mineral and Missoula Counties. The area is defined by the significant rise of the Grave Creek Range and the namesake Petty Mountain, which anchors the southeastern portion of the quadrangle. Most of the terrain is protected within the Lolo National Forest, characterized by a complex network of timber and access roads such as Petty Creek Rd and W Fork Petty Creek Rd that follow the natural drainage patterns of Petty Cr and its many tributaries.

For those tracing the history of water management and land use, the presence of Moulton Reservoir Number Two at the southern edge suggests a managed landscape, while features like Martin Spring and Peppard Gulch highlight the specific topography that influenced early mountain passage and settlement. Modern transit is represented by HWY 10 and the Alberton Frontage Rd, which parallel the river's path through the narrow valley floor.
