Detailed Description
In areas not completely blanketed by tephra from the explosive event, impact marks were obvious where large fragments of molten lava (spatter) had landed on the rim of Halema‘uma‘u Crater, then bounced or slid to their current positions. In this photo, two large pieces of spatter, 45-60 cm (18-24 in) across, can be seen to the upper right and lower left of the GPS unit. The slightly smoother circular features to the right of these fragments show where those bombs initially hit the crater rim.
