About this map

Triangle Lake serves as the central focal point of this western Oregon landscape, where the waters of Lake Creek and its many tributaries converge. The rural settlements of Blachly, Horton, and Post anchor the community, connected by Horton Rd and Post Road as they wind through the drainages of the Coast Range. Education and recreation are centered near the shoreline at the Triangle Lake Sch and the Blachly Lane Picnic Area.

The terrain is defined by significant elevations such as Elk Mountain and Little Elk Mtn, with a dense network of watercourses including South Fork Lobster Creek, Swamp Creek, and Bear Creek carving through the ridges. This mid-1980s survey illustrates a region where the natural environment and local infrastructure are closely tied to the complex hydrology of the lake basin and its surrounding timbered slopes.
