Holiday Valley

Here is a link to a nice article on Holiday Valley. Holiday Valley isn't the biggest place,but I think it skis bigger than the stats suggest

This is my local hill. The infrastructure is great and it’s well managed. They make a ton of snow and do a good job of it. Even though it’s short, you can do laps off multiple high speed quads and ski a fair amount of vertical in a short amount of time. There isn’t much steep terrain, but it’s a fun place to ski when the snow is good.  There are some good tree shots hidden and off the map. If you’re around on a weekday, Holimont is a great spot to check out also. They get a lot less traffic and don’t have night skiing so the snow is usually in better shape.

Holiday Valley gets a lot of traffic, though. It’s the best and most consistent resort that’s close to Toronto, Cleveland, Buffalo, and Pittsburgh. I’ve been told that they actually have the most skier visits in NYS, but I don’t have the stats to back that up. It wouldn’t surprise me. They have a pretty well run real estate and rental business that gets a lot of people coming up for long weekends and they have a bunch of packages that make ski vacations fairly reasonable without much travel for people within a 5 hour drive.

Sounds like Holiday Valley isn't done making sure the snowmaking and other infrastructure keeps up with the times.  Latest price tag is over $3 million.  They have 800 snow guns for just over 250 acres, with another 40 acres natural snow (OnTheSnow).  That's a lot of coverage!

Holiday Valley’s powerful snowmaking system was expanded with 107 new HKD low energy Impulse snowguns.  These were installed on Bear Cub, Maple Leaf, Falcon, Champagne, Mistletoe, Independence, Boomerang, Shamrock and Northwind.  With 351 automated snowguns and almost 800 total snowmaking guns, Holiday Valley has the largest and most powerful HKD automated snowmaking system on the East Coast.  Automation has the advantage of quick startups and shut downs, so even if favourable snowmaking temperatures exist for just a couple of hours, the system can make snow efficiently.  The automated snowmaking system also has weather stations that monitor temperature and humidity so the guns can automatically and individually adjust to changes.  The result is a greater quantity and better quality of snow made using less energy.
 
The grooming crew has added a new Pisten Bully 600 winch cat grooming machine to their fleet.  This machine has a blade for moving large quantities of snow and a tiller to smooth out the surface like other groomers, but it also has a rotating arm with a winch cable that attaches to an anchor point at the top of the slope.  This allows the winch cat to groom uphill on steeper terrain resulting in a smoother, more consistent snow surface.
 
The four glades and several tree trails have received a thorough cleaning out, making them more fun than ever.  Crews have been smoothing out the forest floor by filling in gaps and sharp angles and doing light pruning to open up the woods a bit with the goal of creating healthier tree stands, better tree skiing and more access to powder.
 
The Mountainside Grill, Holiday Valley’s main cafeteria, has been redesigned for easier access, better traffic flow and a fresh new menu.  HolidayValley.com will have a whole new look and improved user-friendly ecommerce.

Also with 43% of the guns being automated with being able to adjust the water air mixture and the ability to turn on or off a bank of snow guns very quickly also helps with snow output.
