FLAGSTAFF – Flagstaff Ranger District is closing the Lava River Cave Friday and Saturday September 6 and 7 to use several pieces of heavy equipment at the location as it continues an improvement construction project approximately 15 miles northwest of Flagstaff.
The entrance to Lava River Cave. The short, steep descent into the cave is rocky. A short distance past the entrance the cave is completely dark. Lava River Cave, 14 miles northwest of Flagstaff, Arizona, is a mile-long lava tube cave was formed roughly 700,000 years ago by molten rock that erupted from a volcanic vent in nearby Hart Prairie. The top, sides and bottom of the flow cooled and solidified first, after which the insides of the lava river continued to flow emptying out the present cave. – Photo by Brady Smith, August 19, 2015.
