Trip purpose: Cartographic objectives in Upper Thunder River
Areas of Cave visited: Upstream Thunder
Trip participants: Bob Lerch, Joe Sikorski, Isaac Smith and Dan Lamping

We began looking for tie-in stations near the shaft. It turns out that the beginning of the Angel Pool Passage (T survey) was never sketched. A survey line was run through it as part of the first survey trip of the CCC, but there’s no sketch. So, we assessed how much passage needed to be drawn and found tie-ins. This will be a full day’s work in the future. read more

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. read more

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. read more
