Episode 13 fountaining at Kīlauea summit

The closed portion of Crater Rim Drive, just west of the active vents, has been covered by a deep layer of tephra falling out downwind from the recent lava fountains. In this section, the deposit is only a few inches thick, but farther down the road the tephra has accumulated into drifts that are up to about a half meter (or half a yard) thick.
