We decided to see if the cave was still plugged up with debris, or if it had washed open with the 2011 high runoff. There is a massive log that jammed up the entrance in the big runoff of 2005, and doesn’t allow people to reach the historical rock collapse from decades ago.
Today we poked around, looked at the water sinking in the stream bed on the left entrance and right before the log in the right side, and pushed a few sticks around. The big log is still as jammed as ever, and there is no way to get over the top of it. The thing is at least 24 inches in diameter and would take a chainsaw to make a dent in it quickly. Probably not worth that effort unless we knew the rock collapse inside the cave were clear, which wasn’t the case for decades before things plugged up. I’ll let the bugs and mold keep doing their work for a while longer and go after some easier projects. We did find the entrance was still holding some ice and snow in late June.
We don’t give up easily when there is a known cave to get into. Jeremiah jammed as far as he could down the left entrance, deciding it was a no-go. And I found a little hole before the log that had washed clean of dirt. After dragging out some rocks and sticks, I took this picture by holding my arm down the hole. It appears the water keeps going, but it would be an endless dig to fit a person. This “passage” is only a few inches high, the stick is probably about the size of your finger. Given this location is five or ten feet upstream of the log that we can see is twenty plus feet long, we decided to move onto other options for our day. We’ll keep checking back later.
The 2011 runoff did bring down a sign from upstream somewhere, and lodged it in the brush along the drainage. Interesting to see how far that makes it in the future.
This is a very large, well known sinkhole. There is an active mine claim in the area as well, so don’t collect anything if you visit. At this point in a low runoff year, a small stream runs down the side of the sink and ultimately dissapears into the ground. The spring the water comes back out of is known, and quite a ways away. I just wish the top end wasn’t full of rocks and dirt, I would like to visit the rest of the system in the middle.
We poked around just a little, and found that there was still ice in the mine shaft. Someone is convinced there is a reason to mine here, but I’m not seeing a good reason. Oh well, some people think I have strange hobbies also.
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.
