Six years ago I was on the Big Island of Hawaii leading a group of undergrads from Lake Superior State University on a geology field trip of the island. It rained on us a lot that week – no fun since we had planned to camp in tents to save money. Not that it put a damper on our desire to see geology in its natural habitat…
For today’s outcrop I’ve selected a couple of exposures of lava flows from the 1969-1974 Mauna Ulu eruptive sequence. First some nice surface forms of a’a and pahoehoe:
Along the shoulder of Chain of Craters Road, it’s now possible to see a cross section through the upper part of this flow field, including some lovely lava tubes.
And finally some flora, for the biologists out there.
