Since the weather was chilly, March first was a great day to be underground, so that’s where members of CAMN went.This year’s class of future Naturalists met that morning for a tour of Blanchard Springs Caverns. Afterwards our president/resident geologist, Darcia Routh led an exploration of the area around Blanchard SpringsDarcia discussed major geological features and the karst topography that allows the formation of caves and sinkholes throughout much of the Ozark Plateau. There was also a bit of roadside fossil hunting in a couple of different locations on the way home. This year’s Earth Science trainees first experienced some sandstone features on Petit Jean Mountain in the Arkansas Valley Province and are now familiar with the type of limestone bluffs that abound in northern Arkansas. This lively group was eager to learn and gathered a lot of good information during this field trip.
