a post from last January's Geo 365 series. The sandstone, though, is a little puzzling to me. In the lower middle, there's a lighter-colored lobe with less fragmental basalt. This may represent a spot into which the pillows didn't push, or perhaps a diapir-like "intrusion," where the sand rose in one place in response to being pushed down by the denser basalts elsewhere.
