Several routes at the Lake were climbable but still with thin conditions this morning after the mercury dropped to 18F last night. Unfortunately, all that is changing again this week no thanks to the bright sun and temperatures forecasted in the mid-to-high forties this afternoon. The temperature is supposed to drop back below freezing every night the rest of this week but that will probably not be enough to rebuild by the weekend as highs during the daytimes will be above freezing and partly sunny. 20 Below Zero Gully at 8:15 a.m.on Nov. 21, 2017.
