I agree that uphill par 3's are more out of fashion, so views or water features can be utilized. Too bad, I love uphill/blind approaches.
I also think #5 at Pebble was a very good uphill par 3. Now there are none at PB.
An all-world uphill par 3 is #14 at Rolling Green. ~200 yards, across a chasm to a NADER-ish green with death right (chasm).
The hidden gem Mark Twain (Ross muni in Elmira, NY), mentioned also by Mike C and Brad K in the past, has all 4 par 3's uphill. #11 is 200+ uphill to a severely tilted green. #7 was a good one, too.
