Volunteers assist with geologic mapping, lava sampling, and recording field observations.
They help with geodetic and geophysical measurements and studies of inactive parts of the volcano. Computer savvy preferred. Applicants must be in good physical condition and be willing to spend a day hiking over uneven ground in the rain with a heavy pack. Applicants should not have respiratory or other health problems that might be aggravated by exposure to volcanic fumes or intense heat. They must provide their own field gear, including a large-sized day pack, raingear, and sturdy, leather hiking boots.
