This was an old post (05/2007) from Len that apparently knew where 89052 was located, and was looking for more detailed information on individual neighborhoods within it. I'm only responding to give you an FYI, you've also posted a link to an even older zip code map.
The zip code changes made in 2006 didn't effect 89052, but there were other parts of Henderson that were, and I wouldn't recommend using it since it's out of date. It could cause some confusion as some boundaries changed and a new zip was added.
Just a heads up for anyone else that might view this thread.
