Basalt with ropy-lava texture, Hawaii


I collected this on family vacation on the big island, Hawaii, in ~1986.  I was struck by the freshness of the ropy lava in the landscape of Hawaii.  The patterns and directions are amazingly complex, not at all as regular as I may have once thought.  In places the ropy lava forms steep descending micro-waterfalls of pahoehoe, ‘frozen’ in action.  I like this rock because more than any it provides a 'feel' for flow of viscous materials.
