Geo 730: May 24, Day 510: "Bandon, We Have A Problem" I

In the parking area near Bandon's south jetty stands an interpretive sign similar to dozens scattered along Oregon's coast. The only substantial variation between them is the placement of the "You Are Here" flag. As I've mentioned before, one might guess, with the heavy coverage of these signs in low-lying areas near the coast, that some sense and restraint might be shown with respect to development- particularly of housing- in these areas. And, as I've mentioned before, one would be disappointed...

Geo 730: May 23, Day 509: The View Southwest

Looking southwest from Bandon's south jetty, you can see the numerous sea stacks that are so characteristic of Oregon's southern coast. The rock unit here is Otter Point Formation, a highly variable and highly faulted melange. The combination of rock variability- from poorly consolidated graywacke and serpentinite to very tough blueschist- and abrupt transitions between them along with fracturing due to faulting results in extremes of differential weathering and erosion. The end product is a grand coastline that is as nice as any I've seen elsewhere.

Geo 730: May 22, Day 508: La Jetée

Looking out along the south jetty of the Coquille River at Bandon, the blueish, schisty texture of the boulders is evident in the foreground. Over on the left, Dana is hunkered down looking at, well, something. There are scads of pretty minerals to find, though many of them I'm unable to identify on sight alone. And to clarify the allusion in the post title, there aren't any monkeys here, let alone twelve of them.

Geo 730: May 21, Day 507: A Logical Question

Looking across the mouth of the Coquille River to the north jetty, Dana asked a perfectly logical question: "Is it made of blueschist, too?" I had not considered the question before, and I honestly don't know the answer. Given what I can see at that distance- basically color alone- it looks consistent. And certainly, given the circumstances of construction, I'm guessing both jetties were built together. It wouldn't make sense to only have one for some period of years. Since a quarry close to the water was established to supply the stone blocks for the south jetty, it would make sense that the same quarry was used at the same time to supply stone for the north jetty. So I'd be willing to bet a small amount that the north jetty is blueschist, too, but I'm just guessing with logic. I don't really know. I *do* know that people sometimes visit that light house, so that jetty probably isn't too hard to get at... ROAD TRIP!
