A short side road takes you to the fascinating Fleener Chimneys. This spatter cone is the source of the rough Devils Homestead aa flow. It was created as erupting globs of molten lava piled up on each other like sticky oatmeal, leaving a 50 ft (15 m) deep chimney behind in the center. Picnic tables at this site are shaded by junipers. The tables were constructed by the Civilian Conservation Corps more than sixty years ago! The massive logs were obtained at Oregon Caves National Monument, and the rocks gathered locally. An accessible restroom is also available here.
