What is the elevation of Mexico along eastern coast?

Mexico's eastern coast is generally low-lying, with elevations typically ranging from sea level to a few hundred meters above sea level. The coastal plain is widest in the northern part of the country, where it stretches for hundreds of kilometers inland, and narrows towards the south. Along the Gulf of Mexico, the coastal plain is interrupted by several mountain ranges, including the Sierra Madre Oriental, which runs parallel to the coast and reaches elevations of over 3,000 meters in some areas. In the southern part of the country, the coastal plain is narrower and the mountains come closer to the coast. The Yucatán Peninsula, which forms the easternmost part of Mexico, is a low-lying region with an average elevation of around 20 meters above sea level.
