A larger area of the lava field than my first small test. It includes the same area as the small test, plus additional area off to one side. The patch of asphalt in the middle of this is a service road that cuts through the lava.
Again this was made using near-orthogonal images taken with a camera suspended from a kite line. Estimated height above ground was 50-100' for the bulk of the shots. At the bottom end of the synth is the trail of shots where I brought the camera down, so the altitude on those is considerably lower.
