But global warming...
OK, I'll hold your hand. Try not to get lost.
Warmer oceans mean more moisture in the atmosphere. More moisture in the atmosphere means more precipitation in the mountains, in patterns that are hard to predict from year to year. More precipitation in Sierra Nevada means more snow in the winter, which means it takes longer to melt out. Some resorts milk the last dollar out of die-hard skiers by putting on a drinking party in July. It appears from your content that they are now marketing to climate change deniers as well.
From Squaw's webpage, it appears that they will have the tram open and maybe two chairs up high. For that they are charging $79, the discount price if bought online (cheaper if you are a senior like me). "*Online only. Save when you purchase in advance. Don't delay. There's limited quantity!"
