Yes..
Ranger is there until 10pm. After that, you need to park in reserve storage/parking near entrance.
The ranger is there till very late. If the gatehouse is locked up, use the radio to call the ranger. They will check you in.
If you didn't make it. You park in the reserve storage/parking near entrance to park. Will see a black gate. Park to the left. Then in morning can pull down to entrance booth and sign in then.
What do you mean by open?
