Allie Spring Cave

Allie Spring Cave is located in eastern portion of Pulaski County in the Mill Creek drainage area. In 2014, the Missouri Caves and Karst Conservancy (MCKC) began managing the cave for the landowner. A bat-optimized gate, constructed in accordance with Bat Conservation International (BCI) standards, was installed to prevent vandalism, discourage unauthorized visitation and preserve remaining speleothems and archeological materials, In addition, the gate serves as public safety measure in this cave that is highly suseptible to flooding.

A Long Wetsuit-Mandatory Entrance

Allie Spring Cave’s small, tight slot entrance leads to an 850-foot long wetsuit mandatory mud- and-cobble crawl. At the end of the challenging entrance passage, the cave opens up into highly decorated, pristine, going borehole, which continues for several thousand feet to a terminal sump.

Further exploration of the cave in the last year, has led to new discoveries, some of which are shown below.

On-going Survey Work in the Cave

In spring of 2015, survey teams made several trips to the cave and pushed the length of Allie Spring Cave to 3100 feet and in September, multiple survey teams added more than 1900 feet, bringing the total interor survey to just under one mile.
