Pillows, Pillows, Everywhere

Today, we spent nearly all day mapping and sampling one pillow quarry. We found that the pillows are highly varied in size, shape, and orientation. Todd is interested in understanding the relationship between pillow morphology and the physical properties of the magma. He hypothesizes that magma viscosity plays a large role in controlling pillow size. To test his hypothesis, he and his trusty field assistants (Adam and Rob) measured the dimensions and orientations of several pillows. They also sampled the interior and glassy rinds so that Todd can analyze the geochemistry when we return to the States. Tomorrow = another day = another quarry.
