We watched a snowmobile center punch a large steep bowl just north of Current Creek Peak. ( tower mtn? Or above Roundy Basin). We were standing about 3 miles due East. As the rider approached the top, the slide began. It did not move fast nor did it appear to step down below the 12-14” of new snow. We could see the black rider slowly traveling down and about mid slope seemed to stop. We could see a second black dot appear slightly below which we believed was the sled. There were some other riders at the base of the hill and we did not go investigate further. Hopefully more info will come forward.
