What effect is Sequestration having on the parks?

Yellowstone planned to open late, due to snow pack and the "reduction" in funding, but the Chambers of Commerce in Cody and Jackson raised enough money to pay the costs for WYDot to plow the snow off the roads. The road from Cody opened last week, and I believe the road is now opened from Jackson. Only the Beartooth Pass route isn't open, and it normally doesn't open until after Memorial Day.

I think the Park is curtailing a few things but nothing that most visitors would notice.
