5/31/10 – Latest stream level data from Carroll Cave

I collected data from the stream level data loggers on May 31.  Attached are PDF files showing graphs.  There is a very large spike in the river level between May 14 and 24. Looking at the raw numbers from Thunder River: 5/24 at 4pm - 4 feet 5/15 at 1:15pm - 17 feet 5/17 at 6pm - Falls below 17 feet 5/20 at 1am - Hits a minumum of 3 feet, then starts to rise again 5/21 at 2:15am - Hits 21 feet 5/24 at 8:45pm - Falls below 2 feet. The data for UL2 shows rise and fall times within hours of the Thunder River times.

4/17/10 – Report from Trip to: Upstream Thunder

Trip Leader name:  Jeff Crews Trip date:  4-17-10 Project manager:  Bob Lerch Trip purpose:  Survey in Upper Thunder Side Passage Areas of Cave visited:  Upstream Thunder Trip participants:  Brett Bradshaw, Peter Chollet, Tyler Allen, Laura Sisken Entry Time:  12:00 Exit Time:  20:00 The trip report:  After some bumbling around we were able to get on the road a little later than we wanted.  We arrive at the shaft right at 11:00 and in an hour had our gear sorted out and the rope rigged.  All of our gear was nice and clean since we had followed the FWS decon procedures. We headed up river to the side passage we've been working on the last couple trips.  We were able to find a well marked station and mapped about 70 feet of complex breakdown, crawl crounch, walk canyon.  Survey was halted at a neat 4 foot water fall that required a tight squeeze to reach.  Above the squeeze was some very sketchy breakdown with the lower part of a dome visible.  It may be possible to move some rock and...

1/30/2010 – Survey Side passages in Upper Thunder

Trip Leader name:  Jeffrey Crews Trip date:  1-30-2010 Project manager:  Bob Lerch Trip purpose:  Survey Side passages in Upper Thunder and introduce new cavers to Carroll Cave Areas of Cave visited:  Upstream Thunder Trip participants:  Adam Reab Dave Hengst Laura Sisken Brett Bradshaw Krista Bartel Ian King Kiley Bush Joe Nicolussi Tyler Allen Andy Free Entry Time:  11:00 AM Exit Time:  9:00 PM The trip report:  Several of the newer members of MSM had found the Carroll web page and were talking about the cave at a meeting.  I offered to lead a trip and given the size of the response I thought it would worth running the trip as a "grotto" trip using the CCC group access policy.  The plan was to stay Friday night at the school house and get up early and drop in.  This would give us plenty of time to get a large group into the cave, have a short tour around T-junction before heading up to some unmapped side passages past The Bone Room. Well as the date for the trip got closer, camping...

1/30/2010 – Survey and charcoal packet swap at DL8

Trip date:  1-30-2010 Project manager:  Ben Miller Trip purpose:  Hydrology -to change charcoal packets at DL8 Areas of Cave visited:  Downstream Thunder Trip participants:  Bob Lerch, Andy Lerch, Josh Brewer Entry Time:  ~1:30 pm 1-30 Exit Time:  3:30 am 1-31 The trip report:  This trip was to travel down to  DL8 to change a charcoal packet placed last September.  A new set of dye injections was set to occur on Sunday the 31st and so we wanted to change this packet before a new round began.  We arrived at the silo and met Spike's group preparing and headin into the cave.  Once they had gotten along their way we entered the cave, changing the packet near the entrance and then heading downstream.  We made our way downstream stopping at DR1 & DR 4 to change charcoal packets.  We did notice the water was about 1.5 feet higher than normal base flow which did make the current a bit stronger than normal.  Swimming on we eventually made our way to Jerrys Cairn area where we crossed to...

1/17/10 – Biology trip to Convention Hall

Trip date: 17 Jan 2010 Project manager: Bill Gee Trip purpose: Biology - examine existing bait sticks and plant new ones Areas of Cave visited: Convention Hall Trip participants: Bill Gee, David Ashley, Zach Copeland, Michael Voltz Entry Time: 10:30am Exit Time: 7:30pm The trip report: This trip started with a conversation between Eric Hertzler and David Ashley. Eric was planning a trip to do some biology work, mainly planting additional bait sticks in lower Carroll River near the Mountain Room. When he realized all the bats are in that area, he changed plans and some more people came on board. Eventually 11 people signed up, though two dropped out. I had been caving on Saturday, so I camped overnight at the schoolhouse. Jon Beard, Eric Hertzler and Josh arrived at the schoolhouse a bit before 9:00am. David Ashley and Michael Voltz arrived a few minutes later. we chatted for a bit while waiting for Zach and his friends to show up. Eventually they did - they had been waiting up at the...

1/16/10 – Biology trip Upstream beyond Round Room

Trip date: 16 Jan 2010 Project manager: Terry Defraties Trip purpose: Place rescue cache, check evacuation routes Areas of Cave visited: Upstream beyond Round Room Trip participants: Bill Gee, Terry Defraties, Jeff Grigg, Lori Schultz Entry Time: 9:15am Exit Time: 8:00pm The trip report: This trip had four goals, all of which were met. We placed a cache of rescue gear in the Round Room, we downloaded all data loggers, we changed out some dye trace bugs for Ben Miller and we surveyed evacuation routes beyond the breakdown pile in upper Thunder River. I arrived at the schoolhouse about 6:00pm. After setting up the camper and having dinner, I went up the hill to service the rain gauge data logger. I suspected its battery was low and I did not want to take the time to change it while others were waiting to get into the cave. The data on the logger was downloaded and I replaced the battery. I was right - it read 2.97 volts which is fairly low. It would probably not have lasted more than a...

12/31/2009 – Annual report from Stream Level project

Hello everyone - The attached JPG files show the full year of stream level data for 2009. A few notes: In order to make nine graphs big enough to be useful, I divided them into four groups. Group one is the rain gauge data, surface temperature and cave air temperature. Groups two, three and four are temp and depth from Thunder River, Carroll River and UL2 respectively. All of the graphs use the same horizontal scale. If you print them all out and stack them vertically, they will line up. The flat lines in the middle of the graphs for rainfall and surface temperature represent about 6 months when that data logger was out of service. The graph for cave air temperature has several spikes in it. These are caused by handling the data logger when it is downloaded. They do not represent real cave temperatures. If you want the raw data, send me an email. I can provide either .HOBO or comma-separated value files. The HOBO files are what actually comes off the data loggers. You must have a...

12/31/09 – 2009 Survey Trip Reports

Carroll Cave Survey Trips – 2009 Submitted by Bob Lerch In all, there were ten survey trips in 2009. Spike Crews previously submitted a report for a trip in April, 2009. Mar. 21–Andy and Bob Lerch and Ben Miller headed to UL3 to mop-up some leads that were nearly seven years old. One lead was past the unfortunately named Burrito Breeze Room, located deep within the central maze passages of UL3. The other lead was a small tube on the western perimeter of UL3. We started on the western lead and made quick work of this small, but dry passage that forms a meander loop, joining the main passage after only 3 shots. We then headed to the Burrito Breeze area and initially did some mop-up in low, muddy, mazey passage. With the unpleasant stuff out of the way, we headed into a small, sandy, crawling tube that promised to go nowhere fast. However, after a few shots of ever smaller passage, we realized we were heading for a too-tight lead in the western maze. Eventually, we had to bag it as the...
