It is said that the third try is a charm and that’s what Bridger-Teton National Forest officials are hoping for today. Over the weekend, the Teton County Park and Recreation snow groomer became mired in the slushy snow about four miles up Cache Creek which is where it still remains. Tuesday, Forest Service Spokesperson Mary Cernicek says a Forest Service bulldozer was sent up to attempt to pull it out, but that attempt failed. Then yesterday, she says a cat excavator was contracted to go up and try again. In the process, the snow gave out under the machine about three miles up the canyon and it plunged end over end coming to rest in Cache Creek. Cernicek says the operator came out of the incident with only cuts and bruises. Today, a team of hand shovelers are in the canyon trying to dig out the excavator and possibly the tiller behind the grooming machine so that they can be brought out. Cernicek says the operation may require brief closures of the canyon, and hopes are that this third effort will succeed.
