|The Lake Yojoa volcanic field consists a group of Pleistocene-to-Holocene scoria cones and collapse pits at the northern end of the scenic north-central Honduras lake (Williams and McBirney, 1969). The volcanic field has produced rocks ranging from tholeiitic basalts to trachybasalts, trachyandesites, and trachytes. The principal NE-trending chain of cones cuts through Cerro Babilonia, the 1090 m high point of the volcanic field, along the same fault pattern that bounds the limestone mountains bordering arcuate Lake Yojoa. Most of the pyroclastic cones, consisting of basaltic scoria and agglutinate, are 100-200 m in height and several contain well-preserved craters. Lava flows radiate in all directions from the cones. The longest flow traveled northward to the village of Río Lindo, where a waterfall cascades down the terminus of the flow. A few Quaternary lava flows occur in the Sulu graben along the Carretara del Norte north of Lake Yojoa.|
