A cluster of rhyolitic lava domes lies on the northern end of the Guadalajara Mesa about 20 km N of the city of Guadalajara. This area is located just beyond the SW end of the Jalpa Graben and lies along the boundary between the Pliocene-Quaternary Mexican Volcanic Belt and the mid-Tertiary Sierra Madre Occidental volcanic province. The Northern Guadalajara Mesa lava domes were erupted through Pliocene ignimbrites forming the mesa. The highest dome, Cerro Jacal de Piedra, lies south of Cerro el Chicharrón. A K-Ar age of 1.4 million years was obtained by Spinnler et al. (2000) from Cerro el Chicharrón. Two other domes are located along a N-S-trending line to the east.
