	USGS Photo Glossary: Ropy pahoehoe
		Close view of ropy texture forming on the surface of a pahoehoe flow at Kilauea Volcano, Hawai`i.
		Ropy pahoehoe is the most common surface texture of pahoehoe flows.
		The numerous folds and wrinkles ("ropes") that are characteristic of ropy pahoehoe form when the thin, partially solidified crust of a flow is slowed or halted (for example, if the crust encounters an obstruction or slower-moving crust).

	PAHOEHOE Flows (Site not responding. Last check: )
		The first and most obvious difference is that pahoehoe flows are smooth down to a scale of a few mm.
		Pahoehoe flows are associated with low-effusion rate eruptions and are emplaced at low volumetric flow rates (2-5 cubic meters per second) and slow flow front velocities (1-10 m/hour).
		The low velocity of pahoehoe flows means that the skin that forms by air-cooling is not disrupted during flow and can maintain its smooth, unbroken, well-insulating surface.
