Nickajack Cave
From Wikipedia, the free encyclopedia
Nickajack Cave is one of the most historically interesting caves in Tennessee. It is located in Marion County, approximately 20 miles west of Chattanooga.
[edit] Overview
Today Nickajack Cave is a National Wildlife Refuge and houses a large colony of endangered bats. Visitors may take Highway 156 west from Exit 161 of Interstate Highway 24 for 5 miles to the entrance to the Maple View Recreation Area and Nickajack Cave Wildlife Refuge. From the parking area, it is a 0.2 mile hike on a well-marked trail to the cave entrance. An observation deck allows visitors to view the cave entrance and to observe the bat flights, in season.
[edit] Nickajack Dam
In 1964, the Tennessee Valley Authority (TVA) began construction of a new dam about one mile downstream from Nickajack Cave. By 1967 this dam (Nickajack Dam) was complete and the lake (Nickajack Lake) backed up into the mouth of Nickajack Cave, leaving only the top half of the entrance visible. Despite this, the cave entrance can still be seen from nearby State Route 156.
