I climbed though butchered birds at the top of that pinnacle once. Are you sure they aren't just hanging out and snacking down? I don't remember there being anything that looked like it would be a good place to nest there. They also nest about 4 months ago so it's unlikely.
When there are arms still holding a quickdraw or a foot still inside a rock shoe and so forth -- warn us then. Outside nesting season to scare us, you'll need a bigger bird.
