GEOL 111 Field Trip
Photos below are from the 20th October 2010 field trip of Steve Lundblad. Students practiced taking temperatures of lava flows that were a few days old, using a thermocouple. The group then hiked uphill to active pahoehoe, measured the temperature with a radiometer, and demonstrated viscosity with a rock hammer.
Photos above shows two different readings (degrees F) of two cooling lava flows. Note the red glow in the crack on the right.
A student measures the temperature of the lava using a radiometer; note the zoomed-in infrared image on the screen.
Above photo, Professor Lundblad breaks open the crust of a pahoehoe flow to demonstrate viscosity and rate of cooling.
GEOL 470 Field Trip
Above, a geology student has carefully positioned thermocouple wires (lower right of photo) as a new breakout of lava occurs. Data is being collected on the rate of cooling of a new lava flow over time.
Meanwhile, another geology student measures inflation of the flow field using a Total Field Station.
