[2] The planners of the festival skipped town with the money, but thousands of young adults showed up at the ski area expecting a second Woodstock.

1972, after resolution of local opposition and legal action, Powder Ridge embarked on a major expansion, which included the construction of the first quad chair in New England, dubbed the "747 lift.

The Zemel brothers also started a business called Fan Jet that produced and sold snow making equipment.

In the 1980s the ski area had a beginner slope that was 1/4 mile long, the Middlefield slope, running the full 1/2 mile length of the mountain and was perennially the first slope to open and the last to close each season, the Glade, which was a narrower run than the others and open less frequently, due to the lack of snow making, the 747, which sometimes had moguls near the top and was considered the more Difficult run, and finally, the Dinosaur, presumably named for the small park of dinosaur foot prints at one of the ski area's entrances.

[2] As noted above, it already did operate in the off-season, but some local citizens were concerned about the increased numbers of cars projected to run on the small country road.

[3] On 23 September 2006, it was announced that Powder Ridge would not operate during the winter of 2006-2007, a time when the ski area was more than $2.5 million in debt to TD Banknorth.

[5] Plans changed sometime over the summer of 2010, and the town chose to retain ownership of the ski area while leasing it to a separate company, Alpine Associates.

[8] In February 2012, Middlefield approved a $1 million bid from Brownstone Exploration & Discovery Park, based in Portland, Connecticut, to buy Powder Ridge.

[13] The park's total area covers 255 acres (103 ha), and includes facilities for freestyle skiing, snowboarding, snowtubing, racing, and snowbiking such as rails, jumps, and a full size half-pipe.

[17] Powder Ridge offers a variety of activities during the summer, including disk golf, synthetic skiing and snowboarding, mountain biking, tubing, and zip lines.
