The community of Amboy serves as the focal point for this section of Clark County, where the transition from the Chelatchie Prairie floor to the timbered heights of Green Mountain and Dunegan Mtn is clearly visible. The landscape is defined by its water resources, with Lake Merwin dominating the northern edge along the Cowlitz County border. This 2013 survey illustrates a region where aviation and water management are intertwined with rural life, featuring both the Mount St Helens Aero Ranch Airport and Walter Sutton's Private Strip. Small industrial and agricultural markers remain, such as the Columbia Tie Mill Pond and various reservoirs like Fassett Reservoir and Leroy Anderson Reservoir. The road network, including the NE Fargher Lake Hwy, connects these dispersed settlements and high-altitude terrain.
