"Uh-oh" said Brenda examining her binding.
It was the way she said it. A tone that immediately makes you stop what you're doing and wonder...Where are we? How long until dark?
The large screw cap for the lateral release adjustment on one of the heel pieces had backed out and disappeared. Along with the internal springs. There was nothing holding the actual binding to the post that remained mounted to the ski.
The situation wasn't too dire. Although we were as far from the trailhead as we were going to get that day, we had a few hours of daylight left, and Brenda could muddle her way back down in half telemark mode.
Resigned to a tedious ski out it was only an afterthought that we tried using a strap to lock the heel of her boot to that remaining post. Surprisingly it worked brilliantly. The lip at the top of the post kept the strap attached. Brenda later said that by the time we were half way down she'd almost forgotten that her binding was broken.
