President Donald Trump plans to eliminate two massive national monuments in California established by former president Joe Biden, the White House confirmed Saturday.

Less than a week before leaving office, Biden signed proclamations establishing the 624,000-acre Chuckwalla National Monument in Southern California and the 224,000-acre Sáttítla Highlands National Monument in northern California. Native American tribes that consider these landscapes sacred had urged Biden to put them off-limits to drilling, mining, clean-energy development and other industrial activity.

Program Notes: Friday, April 11, 2025  at 7:30, join us for Chris Stefano presenting “The Balmat Zinc Mine, St. Lawrence, New York”

The Balmat zinc mines, located in St. Lawrence County, New York, have been producing large quantities of high-grade zinc ore for over a century. Mineral specimen discoveries have been made periodically throughout that history. The deposit has produced world-class examples of calcite, sphalerite, magnetite, and most recently, anhydrite. Collectors around the world have been able to acquire exceptional specimens from recent finds which are easily the best yet. Chris Stefano will briefly describe the geology and history of this important contemporary mineral locality before guiding the audience through a selection of photos of particularly outstanding specimens.
