And a bit of Caltrans folklore. About 1993 I was visiting Caltrans HQ equipment maintenance shop and saw several really beat-up snow blowers - huge engine in back, driving the shredder and snow-tosser in front. 4 wheel steering. I was told they were bought for the 1960 Squaw Valley Winter Olympics back when Donner Pass was two lanes, harder to keep open than yesterday's photos. But then it didn't snow all through December and January, the ski slopes were green grass. The Olympics promoters were spooked out of their minds, you can imagine. Then a few days before Opening Day it snowed like in yesterday's video. This 'excess' batch of plows, new at the time, saved the day. There would have been no access from California's urban areas up over Donner Pass to Squaw Valley if Caltrans hadn't had so many plows that they nearly had one to lead each bus. These plows would be kept for occasional use in similar severe years, they were over 30 years old when I saw them.
Another story. US 50 to South Tahoe and the casinos, was closed for many weeks after a PGE flume failed and landslides blocked the road. There was an alternate back road, several miles, so they sent out bulldozers to pioneer and open it. After a few days, good news, the bulldozers met in the middle. Bad news. The bulldozes were on top of packed snow a considerable height above the surface of the road. It was a while longer before the detour was opened.
