Noticed similar during a visit in low water many years ago. At the time didn’t give it much thought assuming it joined the swims prior to boulder hall. Later down the line i couldn’t help feeling there is a lot more to this area of the cave than meets the eye and possibly more to be discovered there. In the past ive been too quick to write things off and assume others have already investigated, or that the only discoveries to make are at the terminus. Sure i’ve said in the past, the presence of far more in that region can be felt.
