any chance you could do a video of the set up and release of your base anchor?
Here is some video related to my remote release anchor design, at the time I made the videos I was still experimenting and had not built it as a basal anchor yet. Between the video posted above and the videos posted below you should be able to figure it out. It's probably better that I don't post a definitive instruction video for this, only highly experienced climbers should try this and I can't control who watches.
This was made 3 years ago and is how I currently set my basal anchors for woods rec climbs where I want to be able to reset the anchor after I've accessed the crown SRT:
Here's how it's tied, notice the second time I tie it the bight on the release is nice and long. When I actually use this I make the bite even longer. The tail of the rope from the bight is attached to the other end of the rope that I'm climbing on. To release the climber has to pull up the tail of the rope they ascended on, pull all the slack from the bight through, and then release through two slip knots. So it's really three actions to release: pull out the bight, release the first slip knot, then the second. Additionally I always set it so that at least 6' of the pullout line is lying on the ground so that if a limb fell while I was ascending it wouldn't have any chance to trigger the release. An additional safety factor is that under normal forces (not a tree falling on it) it cannot be released when the climber's weight is on the rope, I have tested this several times, it will not release. To release you have to lanyard in and slack off the main climbing rope.
In the video I first posted both legs of the rope didn't quite reach the ground so I used slings girthed together to create the part of the release that is on the ground. It would be very unwise to set this with the belly of the release line off the ground.
This photo shows how I've set a big bight and the other end of my rope is attached to the tail off the bight. What you can't see in the photo is 6 or so feet of rope on the ground to prevent some kind of impact from above triggering the release. Even if the belly of the rope was off the ground a falling object would have to pull out the bight before it would have a chance to initiate the release. So there is a lot of consideration towards making redundant safety features.
This is not an anchor I would ever work off of. It is intended to be used for access only when I want to reset my anchor after I reach the crown.
