How to query for a user-table column name?

Hi List;

I'm researching a db and I want to find samples of some of the data. I know
based on the documentation for the proposed "new" schema that the db I have
access to (the "old" schema) probably has a column in one or more of the user
tables called 'region'.

I'm looking for a way to query the system tables to find all user tables with
a column named region.  Any thoughts, help?


Thanks in advance..
