About this map

Mason Lake and its surrounding glaciated landscape dominate this portion of Mason County, showing a complex network of freshwater bodies and saltwater inlets. The settlement of Little Hoquiam sits on the western shore of the primary lake, while the eastern portion of the map transitions into the maritime environment of Puget Sound. The intricate shoreline of Hartstine Island is visible across Pickering Passage, featuring landmarks such as Jarrell Cove and the community of Hartstene.

Surface water is a defining characteristic of this terrain, from larger basins like Spencer Lake and Phillips Lake to smaller features like Benson Lake and Trask Lake. The map illustrates the specialized landforms of the region, including the Kellums Lake Isthmus in the northeast and prominent coastal points like Graham Point and Sun Point. This 2017 survey details the modern road network, including E State Rte 3, which connects these lakeside communities and coastal settlements.
