[Rockhounds] North Table Mtn., Golden, CO

[Kreigh Tomaszewski]

Just to keep the record straight, I got a response off-list with 
references...

	Cross & Hillebrand, 1885 (USGS Bull.20, p.13-39)

	Patton, 1900 (GSA Bull, v.11,p.461-474)

	Rudy Tschernich's book Zeolites of the World

This list rocks!
