Bore Sump.  More about this section of the cave will be discussed later.  Although these discoveries greatly extended the known length of the cave, exploration ceased in the mid-nineties.  It would be a decade before any coordinated work commenced.

Current Project
In May 2005, a new survey project began, after long-time Webster caver Chris Anderson pulled Ben Tobin and myself into the world of Webster with a photography trip to the Mulu and Pleasure Domes area beyond the Northbore sump.  Under the auspices of the Webster Cave Complex Survey Group, a dedicated team of explorers has since been formed.  Initial trips
focused on survey between the three known entrances of Webster cave and the 3 mile long main trunk, aptly named Webster Avenue.  In some of these survey trips, shot length averaged over 90 ft, and 3500ft days

were accomplished in just a few hours.  Alas!  We knew that these days were numbered, and that Webster had its share of grim passage to keep us all humble.
   An hour from the entrance, Parks Avenue, the largest known side lead off of Webster Avenue, was also one of the group’s first objectives.  The reason  for this was not only survey of Parks Avenue itself, but what lay beyond an inconspicuous hands and knees crawl behind a large piece of breakdown.  This unexciting passage is the beginning of Northbore, and provides access to what may very well be the majority of Webster Cave… if that damn sump didn’t always get in the way.  Anyone familiar with Webster knows that while Webster Avenue, and everything on ‘this’ side of the sump has plenty of beautiful passage (and more than a few surprises that we’re still finding), it’s the great mystery of what lies beyond that draws us back time and again.  Discovered in the mid-nineties by the KCSG, the Northbore sump (aka Mulu sump) provides access to cave of unknown potential.  Beyond the sump, Northbore turns into pleasant walking passage, and before long, an intersection is reached, with the Mulu passage taking off to the left and Eastbore taking off to the right.  Northbore and some of Mulu were surveyed for about a mile by the KCSG.  That survey ended in 10ft by 20ft borehole.  That survey also left Eastbore untouched, being the smaller of the two passages.  Unfortunately, the Northbore sump is a temperamental beast that shuts easily when it 
rains, and can stay shut for years.  Subsequently, it’s easy to understand why all other survey objectives get put on hold when the sump is open.  In the summer of 2005, water levels were low
