The world's only schoolhouse made of onyx.
Slowly being destroyed. David K in front. The road to El Volcan goes over the rise, to the left of the schoolhouse. (7-24-00)
Just over 4 miles from El Marmol, the process of making onyx can be seen here. (7-24-00)
About 5 of these tiny springs can be seen on this
hillside. The geyser and 'onyx dome' eluded us on this trip. (7-24-00)
What Lorenzo and I couldn't find! It is up the arroyo the
road crosses 2/10ths a mile before the hillside with the springs in my photo.
