Only available from Muir Way, this unique map undergoes a meticulous process where it is printed, heated, and vacuum-formed over an intricately detailed 3D mold. The result is a map that allows you to visually and tactilely explore the Buckeye state, from Lake Erie to the Ohio River.The colors on the map represent the different geological features within the terrain. Framed maps do not have glass or acrylic over them, so you can touch the map and explore its intricacies.   PLEASE NOTE You will love this map if you embrace its anomalies. When the plastic is heated and stretched over the 3D mold, the image may be altered, causing warped lines and text around higher elevations. The fine print on plastic is not as sharp as on paper, sometimes rendering very small text illegible.
