    Fabulous video! Beautiful cave! Brings back lots of memories... We did the first thru-trip from bottom up and free-climbed the whole thing. Jeeze!...

    • @DerekBristol
      @DerekBristol  Před 3 lety +2

      Hey Pete. I mention your amazing through-trip in this video: czcams.com/video/xQEOPJgyZaU/video.html . I didn't realize there were no fixed ropes. I considered everything might be climbable except Connection Falls, where the top portion looked like it would be pretty sporting. I've been curious how many through-trips you've made, the fastest time you're aware of, and maybe the oldest person to have made it through. Thanks!

    • @peteshifflett9271
      @peteshifflett9271 Před 3 lety +12

      Hi Derek, Connection Falls wasn't too bad because of the great friction. Upstream from there the ropes were coiled at the tops of the pitches and we didn't have our ascending gear with us, but we were very familiar with the cave. The climb up to the Lunch Room was especially difficult. The fastest trips were when Don Coons and I did a solo cross-over trip in 1985. We'd been surveying for several weeks and were in pretty good shape. He did it from the top down and I think it took him about 7.5 hours. I went from bottom up and it took me about 8.5 hours. Coincidentally, we crossed at Connection Falls! I've done 8 thru-trips, 2 bottom up, 6 top down, the last being in 2005 when I was 50. Warren Anderson was also on that trip and I think he was 54. Good Caving!

    • @DerekBristol
      @DerekBristol  Před 3 lety +8

      Awesome! I figured that cross-over was probably the fastest. This trip was 9 hours. None of us had been all the way through, so none of us had seen from B-52 Falls down to the start of the GCoD. We had been surveying from the top and bottom though and were very familiar with the rest. I am 51 and being the oldest on a through-trip hadn't occurred to me until talking to Bob Montgomery. Maybe I'll need to do it again in a few years to set the record. There haven't been many through-trips lately - maybe only 3-4 since your trip in 2005. Bob has been concerned about losing some of the knowledge about the cave as we transition to the next generation. This renewed exploration effort should get a lot of people re-familiarized. I'll PM you with the expedition report once completed.

    • @peteshifflett9271
      @peteshifflett9271 Před 3 lety +5

      I figured you had a quick trip, you were all moving real smooth in the video. I've thought about doing it again but at 65 it would be quite a bit more risky than usual. I'm very glad to hear you're getting people re-familiarized with it. In 2005 I compiled a comprehensive digital record of everything ever written about the cave, all photos ever taken, thru-trip directions, and the entire survey. I distributed it to as many people I cold think of. Let me know if it would be helpful to you and I'll send you a copy (~1GB).

    The summer of 2003, several months after the NSS acquired the upper entrance of Great X, Kristen Bobo, Bill Putnam, John Swartz, Jeb Blakley, and myself dug out the sand crawl that leads to the Great Exit. The next day we were thwarted by route finding, as guide Jeb hadn't been in the cave in 15 years. After a brief call to Pete Shifflet late that afternoon we understood our route finding error. The next morning Jeb & I successfully completed the first through trip of this Super Alpine Cave to be made in years. The video is awesome & certainly brings back the experience I had from years ago of that then 51 year guy. THANKS!

      @@DerekBristol Having a carbide heater on our helmets was a lifesaver at times. IIRC, the deepest down-and-back-up survey trip was Miles Hecker, Paul Hill and me to Connection Falls. You'll need lower water than in your video for a trip like that. I free climbed the falls but since we didn't have a rope, we didn't push further.
      The lower part was surveyed from the bottom up. Pete has that info. It goes much better when the crew memorizes the route thru the Grim Crawl and the harder stream climbs.

      Paul H. here (see Jeb's comment below)
      Kids these days with their fancy video equipment! :)
      Actually, a lovely video!
      As Jeb mentioned, we laid some of those survey points; maybe somewhere in the B survey and up in that dry bypass shown at 11:16. That's not dry looking? Compared to the river it is dry!
      I was noticing the high water too. What was the sequence? Jeb and I did the Grim Crawl from the bottom to check out the route. Then later returned for the through trip that failed. There weren't any signs or pre-rigged ropes and we didn't get good enough rigging directions and ran out of rope. Ooops! I belayed Jeb down one more falls with a piece of webbing I had by sitting in the water at the lip of the falls - Brrrr! Jeb declared it over when he walked down, climbed a few more to find yet another falls - I guess was actually connection falls. I guess we could have climbed down the last few cascades from there, but we didn't want to pull /climb down not knowing if there was actually yet another falls too tall to scramble down with just my piece of webbing.
      Down and then back out from there was hard, and then there was me walking overland down canyon the SAME DAY to retrieve my overnight camping bag I had stashed at the lower entrance to await my coming out the lower entrance. I wasn't going to drive back the 7-8 hours to the Bighorns from Salt Lake before the snows flew, so despite being drained I had to do the hike down and back, and then drive to SLC. I might have been late for work the next day...
      My biggest mistake walking down canyon was picking up Miles' pack too only to NOT meet him coming down the trail, so I had to carry his pack and mine all the way to camp; where would I have left his? I gave Miles more then a few stern looks when I found out he had decided not to walk down too.
      Oh those were the days!

      What was it. The claustrophobia? The water to ceiling height. ? The way the groove you’re crawling down pinches out and you have find another ? There’s a cave in California about 18 miles long it’s alpine and freezing and there’s a similar crawl called the “ lurking fear”. You have this fear in the back of your mind that there’s no storms or rises in the water level even an inch. Of course the water temp is 36* which doesn’t help. The other fear is taking too long and getting cold.

Or Grotto "The Hole in the Wall" All pretty much moved away but a few of us My Guy and I miss being underground and was thinking if you were from here it would be exciting to meet fellow Caver and maybe start getting underground again even if it was mostly my Boyfriend he was the one who got me into it and I know he misses it!

I wouldn't trust taking my full frame Nikon in there. I plan on buying a Sony A7RIII but not for caving. My big question is the lighting. Are you using Sten lights? just the headlamp or additional light sources? Maybe its just the setting on the Sony camera that let you pick up that much light source or smaller passages. Passages in West Virginia are Immense and difficult to light up.

    Fantastic underground water slide. Is the velcro boxwork, or just the intense scalloping of a very active stream? Cherty, too. Primal drums good choice for soundtrack, considering. Also, I left a poem called "Hidden Indiana" on a previous video's comment section when I found out you started your caving career there. I put it on about a week after the video came out. Anyway, it was the video with the emblem "IT GOES" and documented 100 survey shots in Wind cave. Seems no cave you enter goes unextended.

    @davebunnell1 Před 3 lety +1

    Nicely done Derek, it gives a real feel for what traveling through the cave is like. It seemed like so much water towards the top, and not a much larger volume deeper down. I would presume it picks up water from other infeeders but perhaps not? And geologically, it seems strange that the water carved mostly walking height canyons but then not in the grim crawl. Any idea why its so different there, maybe a different layer of dolomite that is more resistant?

    • @DerekBristol
      @DerekBristol  Před 3 lety +1

      It definitely picks up some infeeders along the way. Much of what you see in the Grim Crawl represents only a portion of the water. It's divided into multiple channels. The preferred route follows the maximum water flow, but it's never all in one channel. Not sure what changed with the geology, but it definitely does change. My guess is that the water hits the underlying sandstone at the grim crawl so it's confined to that bedding plane. Same dolomite bedrock though.

      Yes, caves are completely void of light other than that from headlamps. Modern headlamps are pretty bright and efficient though.

    The stuttering on your drone footage is really unfortunate. The shots are beautiful, but the stuttering really wrecks them.

      You're right about that. I thought my CPU was lagging during playback. Turns out the memory card I borrowed (due to a corrupted one) wasn't able to keep up with the record rate. Didn't catch it until after it was uploaded. Won't happen again. There's better drone footage of the same area in this video: czcams.com/video/xQEOPJgyZaU/video.html

      The Grim Crawl has that velcro surface on the FLOOR and CEILING always within a few inches of you as you try to crawl, scoot, swing, slide down or up the low passage.

      The choice is crawl in the mountain water or die near the bottom of the cave... given that you bend down and start crawling knowing there is a way out. The situation seems to motivate people ;)

      Chert nodules. The chert is made of silica, which is far less soluble than the dolomite bedrock.
