in Hanaford Valley, 2023 The valley is divided into three sections, "Big Hanaford", the central portion and considered the largest of the region, "North Hanaford", located near the Lewis and Thurston county line, and "Little Hanaford" around Hanaford Creek. A landform near the Logan District east of Centralia, known as Vinegar Valley, was also known as Little Hanaford. In 1897, the valley was measured to be roughly in length and its width spanning up to , for a total of approximately . The topography of the area is recorded to contain steep but rounded hills interspersed with flat, poorly drained pocket valleys. The valley contains several streams, including Hanaford Creek which courses from the former community of
Coal Creek near the Lewis and Thurston county border to
Wabash. The creek empties into Skookumchuck River outside of Centralia and is considered part of the
Chehalis River watershed. South Hanaford Creek crosses the valley from the
North Fork Newaukum River through Nulls Crossing to the north tributary of Hanaford Creek near the geographic midpoint of the valley.
Mount Rainier can be viewed from the valley. A
surge reservoir is located near the steam plant. Former communities or towns once located in the valley include
Hanaford and
Hurn, which was located approximately to up the landform from Centralia. Several coal mining towns, such as Kopiah, Mendota, and Tono, also existed either within or near the valley borders. ==Geology==
