AirMap Question

[RoarRoar]

Scouting some locations for some future flights I came across this box around kitty hawk nc. Now I know I can’t fly around the monument and national park areas. Can anyone answer what this box is? Sorry if it seems super silly.

Looks like it's an advisory for the Nags Head park.

All I needed to know thanks. That’s what I thought.
