A cold snap and a snowstorm provided the proper conditions for Sun Valley Co. to turn on the snow guns on Bald and Dollar mountains.
Marketing Director Jack Sibbach said snowmaking began Sunday, four or five days later than usual. However, the late start was countered by a snowstorm at the beginning of the week. About eight inches fell on top of Bald Mountain.
"The goal, as always, is to open from top to bottom on both side of Baldy by Thanksgiving," Sibbach said.
To do so means adequate snow on Upper College, Flying Squirrel and Lower Warm Springs runs on the Warm Springs side of the mountain, and Roundhouse Lane, and Mid and Lower River Run on the east side of Baldy.
"We've had a beautiful, long fall, but now that it's turned, we're hitting it hard," Sibbach said. "I just hope Mother Nature is on our side to get open on time."
Rain and snow showers are forecast for the next week, with low temperatures in Ketchum ranging between 15 and 28 degrees F. and high temperatures ranging between 38 and 47 degrees.
