yesterday's shot of Winter Falls, and the ovoid forms look a little bit more pillow-like, but there's still just too much moss and other vegetation for me to be very confident about identifying them. It's more like "suspicious." During the Miocene, when these basalt flows erupted, there was definitely still a marine inlet in the Willamette Valley, though my sense is that sediment deposition wasn't as heavy as during the Oligocene, so pillows in Columbia River Basalt flows are not out of the question, and indeed might be expected. In this instance, though, the exposure is just not defined or clear enough for me to feel any conviction about their identity.
