On September 28, five cavers entered the Arritt Mill Tunnel and the cave opening off it, in Alleghany County, Virginia. They intended to survey and do some photography, so they split up with three starting a survey of west-trending leads off the main passage. A low slit, trending upward, allowed only two of the three to pass and soon became too tight for even the smallest of the surveyors. Tom Spina, one of the remaining backed out feet first, apparently having some difficulty. He presumably was aware of a problem and left the cave "in a fair amount of discomfort." He had suffered two cracked ribs exiting the squeezeway.
