From my views of Bretton Woods (never skied, only seen from the base a couple times recently), the terrain looks nearly perfect for families and a sustained intermediate pitch. It's a very Okemo type gradient...no run out and a moderate pitch. A sustained ramp at just the right angle, along with a strong mountain operations team. Based on many observations, it's a well executed operation without a lot of rough edges, so to speak.
1,200-1,500 vertical feet of moderate slope, located in an upslope zone that will at least get some refreshes more than neighboring areas... it's a good combination for highly rated snow condition quality. On average, the intermediate pitch won't see the ice that a steep pitch will see if all else is equal. Skiers don't edge as hard and gravity doesn't play as big a role in snow conditions. It may not be a 2,000-2,500 vertical foot ski area with sharp relief (Wildcat, Cannon), but I think Bretton Woods is likely a top-tier cruiser mountain based on conditions and operational proficiency.
