involve many long cave dives – nothing of which on such a scale has ever been attempted in
Indiana. Such a connection would likely greatly expand the known lengths of both caves as there are still significant gaps of unexplored cave in between the two systems. Binkley's currently measures around 44 miles (71 km) in length – the longest known cave in Indiana and the seventh longest cave known in the United States – and its known extent is increasing due to the efforts of the ISS. Cave divers led by Dave Strickland have mapped several thousand feet of cave in Harrison Spring – all of which was at a significant depth, and entirely underwater.

254:, the largest known cave in Indiana, the cavers of the Indiana Speleological Survey (ISS) have noted that according to their cave mapping data, water in the Blowing Hole section of Binkley's appears to flow under the bed of Indian Creek, near the Sinks of Indian Creek, and resurge at Harrison Spring. This is further proven by dye trace studies performed in the sinkhole plain containing Binkley's Cave.

The rise pool at
Harrison Spring measures approximately 120 feet (37 m) by 95 feet (29 m). It is within an abandoned meander loop of Blue River. Divers have measured its depth to be about 45 feet (14 m). Harrison Spring has an average discharge of 100 cubic feet per second
