Summary of site:
This wooded doline is crossed by a small stream that sinks in several places. One of the sinks (a narrow slot dug by cavers) ends in a boulder chamber with a number of boulder-defined rifts. The water is believed to drain through into the Inlet 1 series near Artie's Chamber in the Noon's Hole system.
