Discussion: I wonder

what the event insurance carrier would have to say about this.

I have to say, now that I see the picture, I find it less intimidating than what I was picturing based on the (very accurate) descriptions that you and Ian gave. I would probably have gone for it standing if I had spikes, and seated if I didn't. But I'm admittedly nuts. I'm actually quite surprised to see so many people willing to to do it, as most folks I know would pass. Three feet of water seems like a both a shallow landing after a drop from that height, and way more water than you'd want to find yourself in. Doubly dangerous.

I'm never terribly comfortable on dry logs over small streams - lousy balance - and frequently will wade a stream rather than do the log cross. This one just wasn't worth the risk on either front...

I was feeling particularly competitive, as there was a group not far behind me, so I walked the first half and then scooted the second. It must be noted that I often make bad life choices.

I'm accustomed to crossing a log over the Mulpus Brook on the Mystery Blazes loop. In dry conditions I can jump the stream. In the springtime, I take the log. If it's cold enough I can walk on the ice. But once in a while I have to take the log when it's covered with snow. In snowshoes. But it's a far less epic log than the one in the picture.

At first glance the log doesn't look that long, but note the relative scale of the folks on the far bank. No one is jumping over that one....

As for insurance, we signed a waiver. I'm thinking the scope of AR adventuring around the world encompasses this and more on a regular basis, but just a guess. Joe would know.

I thought a photo of the log crossing would be an interesting addition to one's log....
And voila, Untamed Adventure provided one.

Looks long to me. Mulpus Brook is not a river like that (although it probably gets that wide when it spills out over its floodplain, at a couple of inches deep). In the summer there's sometimes very little flow.
