June 25, 2015: 11 River Watchers from Akins, Lanier, and LBJ had their field trip to Inner Space Caverns. As they explored one mile of underground rooms, they learned more about the formation of caves, groundwater as part of the water cycle, aquifers, speleothems, and fossils. After their underground tour, they headed to Blue Hole Park in Georgetown for a swim and lunch.
