 Coaldale is in the southern Anthracite Coal region in the Panther Creek valley, a tributary of the Little Schuylkill River, along which U.S. Route 209 was eventually built between the steep climb up Pisgah Mountain from Nesquehoning (easterly) and its outlet in Tamaqua, Pennsylvania about five miles to the west.The town is virtually joined at the hip to nearby Lansford, to its immediate east—as both were founded as company towns on lands owned by and mined by the Lehigh Coal & Navigation Company (LC&N) while technically "on opposite sides of the county lines".In truth, the history, business situation, and fortunes of not just the two, but of three towns, the third being the nearby Summit Hill, PA located a few thousand feet upslope were tied in decades of co-development because the LC&N had built the western terminus of the nation's second railroad, the Summit Hill and Mauch Chunk Gravity Railway to ship coal out, and opened multiple mines throughout Coaldale and Lansford and the rest of the Panther Creek Valley in the days when railroads were coming into their own.
