The very short bolt ladder (expansion bolts; = only way to the very top) predates 2003 fires: treat with care, the fires were very hot here...
Most of the climbs (Sentry Duty etc) end up on the platform below that capstone boulder. There are a few ways to scramble off the platform, not very easy nor very hard.
Many years ago someone went completely over-the-top bolting on metal steps etc everywhere. I doubt that a simple bolt belay would offend anyone.
But I would recommend the two nearby crack climbs on different boulders more anyway.
