The permit was under Dan Lamping’s name but due to a last minute injury he was unable to participate.
We entered the cave on Saturday morning having everyone at the bottom of the hole by 10am.
Our objectives were to fix the tie-in of UL1 and mainstream, check a couple of things noted on the field notes, and then head upstream to the Round Room to get some better sketches, and add a cross section through the room.

Objective: Survey side passage found on previous trip. Experiment with drone in lower Thunder for checking high leads.
Alex, Josh, and I arrived onsite Friday evening around 9pm. We set up camp and rigged the hole to hopefully ward off the inevitable milling about on Saturday morning. It was a cold and windy night on the surface. I was thankful to have my camper.

Josh, Derik and I arrived at the backdoor entrance around 3:45pm. We immediately started rigging the hole.
Recently we have started rigging the hole a little different. Concern over the strength of the welds on the wall of the silo has lead us to start rigging with a figure eight on a bight with carabiner to the stainless hasp under the rescue hole. We then tie a butterfly with a large loop to the old eyelets welded to the wall. This allows for the rope to fall basically down the center of the shaft. We rappel in and climb out using our Croll on our frog systems as a safety while climbing the ladder. On camp trips such as these, we rig a pulley for hauling camp packs out at the end of a trip. We use a truck to slowly pull the camp packs up the hole. This works out very well, and is tremendously better than trying to haul heavy camp packs after several days under.
