“A very short trail leading to an impressive crater that was once a lake of lava!”— QuinTCM TCM
Mammoth Crater and Modoc Crater are responsible for about 70% of the lava flow in the park. The lava that flowed from both of these craters is also responsible for the majority of lava tube caves found in the park. Mammoth crater once contained a massive lake of lava that overflowed instead of erupted, leaving behind the empty crater. The lava from this crater was highly fluid and traveled all the way to the northern part of the park, creating lava tube caves all along the way.
