Dates of Past Flows

[2liveque]

Anybody know how old the flow(s) is/are that created HPP?

Most of the flows in HPP are only about 300-400 years old and came direct from the summit of Kilauea. The topsoil is very thin...maybe a couple of inches. You can see that from the road cuts along Highway 130. There are probably some kipukas with thicker soil beds from much earlier flows.

Edited to show that the flows were 300-400 years old instead of 200 years and to provide this link from HVO:
