Report written by Dan Lamping:

We went into UL2 to fix a blunder in the Land B4 Time survey, as side passage off UL2 that connects to Convention Hall. This was bad data at tie-in from years ago. There’s some pretty tough and demanding passage to negotiate the whole B4 loop. Both Joe and I having been there, but coming from the other way, had forgotten the climbs and tight meanders in the passage. It was tough enough going in that we considered heading out via Convention Hall, but the climbdown, which we’ve gone up before, was a bit too exposed and slick to try coming down. We reshot the bad survey shot and left. We went back out the way we came, which was easier than going in. We completed this and fixed another blunder further up the passage. This all in support of cartography for the U1 Sheet.
