San Martín Pajapan is a composite volcano at the SE end of the Sierra de Santa Martha along the Gulf of Mexico SE of Lake Catemaco. Von Wolff (1929) reported Indian traditions of "smoke" and fire from the volcano, but Nelson and Gonzalez-Caver (1993) noted that the volcano is capped by thick lateritic soils and lacks evidence for recent activity. A K-Ar date of 1.5 +/- 0.2 million years ago (Ma) was obtained from one of the youngest lava flows. K-Ar dates on the adjacent eroded volcanoes of Santa Martha and Yohualtajapan to the NW range from 3.3 to 1.0 Ma. The summits of both these volcanoes are truncated by large depressions open to the north of erosional and slope failure origin. Hundreds of partially eroded cinder cones dot the southern slopes of the Sierra de Santa Martha.
