The March 5 breakout of the 61g flow is producing active surface flows on and at the base of the pali (cliff). The slow-moving pāhoehoe flow front (foreground) was approximately 400 meters (yards) beyond the base of the pali on the afternoon of May 23. An ‘a‘ā channel (center) made its way down the pali, along with other small breakouts and channels of ‘a‘ā and pāhoehoe scattered to the west of the main 61g lava tube (visible degassing at upper right).
