Thursday, July 9th

The Lost River is one of the finest expressions of karst hydrology in southern Indiana: a base level stream that abandons the surface, travels through a hidden maze of limestone conduits beneath the Mitchell Plain, and returns to daylight near the Indiana Karst Conservancy’s Orangeville Rise. In doing so, it has helped shape an intricate drainage basin within one of the Ohio Valley Region’s iconic karst landscapes.

This tour invites participants to follow that hidden journey from sink to spring, with stops at features such as the sinks of the Lost River, Wesley Chapel Gulf and other significant cave features. We will examine the geologic and hydrologic processes that have shaped the basin, see how those forces remain active today, and discuss the conservation pressures facing this vulnerable watershed.

Bus transportation (non-airconditioned) and sack lunch/drinks will be provided (veg/non-veg options)

Guests should dress comfortably and prepare to do some light hiking ~1 mile and use bug spray to prevent ticks.
