The group had a grand old time in Hawaii. According to USGS geologist Jerry Schaber, who chronicled the Apollo happenings at USGS, one particularly noteworthy moment from this 1970 trip was a hike the group took near an active lava flow. Some members of the group melted the soles of their shoes on still-hot lava. Later, someone boldly poked at the edge of a cooling flow, triggering a re-direction of lava right over USGS geologist Bob Sutton’s boots. And when astronaut Dick Gordon decided to try to take a cooled sample of the molten lava back for his kids, he caught a stick on fire, and tried to put out the flame and cool the sample with some rather crude methods.
