Need a stand-up, easy walking cave? This is one that is good for all of that, with a minor issue. Most years, you have to wade through a deep cold puddle right at the entrance area to get to the main passage. This year we lucked out with the low spring runoff, and were able to simply waltz right into the cave, no wading required. (Do not try to enter the cave too early in the spring, at high runoff the sump pool comes up higher and the water flows out of the cave entrance.)
This cave is a fascinating segment of trunk passage that we cruised up and down. The main upstream passage ends at a large sump, or area where the passage goes underwater. There has been much discussion of why and how this is the case, which is outside the scope of this trip report.
On the downstream end, you end up doing a little crawling to find another small sump. There are a few small side passages and crawls you can wiggle through, but they generally all reconnect or dead end in a muddy mess.
There is about 800-900 feet of accessible cave passage, and as long as you are careful not to slip on the mud, generally a fun place to visit. Make sure and check into the runoff conditions if possible, cold silty water pouring out of the cave would certainly shorten the fun. And in high runoff conditions, you can see that the cave fills to the roof with water.
