It makes sense; you can't drive there when it's covered under feet of snow. And when all that snow melts, the ground is still soggy, flooded, and can't deal with the masses.

Many mountain locations open their campgrounds in June, some roads are not drivable until late June -- and then everything closes again mid-October.
