A Tale of Two Karsts

October 20, 2005

A karst is an area of irregular limestone in which erosion has produced fissures, sinkholes, underground streams and caverns. USU geologist Peter Kolesar is investigating springs in two alpine karst aquifer systems along the Logan River in Utah's Bear River Range. One of these is the main water source for the city of Logan, Utah.
