It looks like all the High Approaches, to PAX start at or above 2500' MSL. Check out this site for all your airfield specifics. I'm not sure I call a 2500' start a high approach.
Anyone offhand know what determines a High approach.

This is an unappealing set of plates and I would not enjoy flying them without familiarity.
For HI-TACAN RWY 06: The profile view picks up the procedure at 2500 MSL for the FAC. When I first looked at it I thought it was some type of abbreviated view, but given that there are three separate IAFs (two of which arc from opposite directions), it appears to be the only reasonable option.
The result is that you have to refer to the plan view for altitude guidance (I've never seen altitude printed on plan view before). I wouldn't be surprised if people routinely come onto final at 7000 MSL vice 2500. Have you seen that, AC2?
At 150 ground speed you'd be falling around 2300 fpm to hit FAF.
