All of the snow will be man made. Ryan Neptune of Planet is building the park. They'll start making snow whenever the temp drops below freezing, which is usually at night in November in Boise. They hope to be open by Thanksgiving or early December. And they will open WITH a park (& not have to wait for snow to fall). There is already a huge water tank at the top of the hill. The park will actually use far less water than a golf course or grass sports field. They'll blow a deep base, like several feet. Planet did this at Hawk Island in Lansing, Michigan & they were the last resort to close last winter. Ryan's got it all figured out. He's built parks all over the world, including X-Games venues and Olympic jumps & courses. The guy knows what he's doing. It's gona be sick!
