Melman on Gold & Silver
October 2003
There was certainly no shortage of attention-grabbing headlines during the past month. First we had the successful initiation of a recall election in California, followed by enormous increases in the price of gasoline in the USA and Canada, then both nations suffered through the worst power blackout in decades, and finally we are witnessing what appears to be the unraveling of the “road map” to peace in the Middle East.

Multiple Use Lands, Symbiotic Relations and Conflict Resolution
April 2016
The automatic discrimination and exclusion of man from nature, like his access and use of the land, presupposes man as a destructive force for change, absent a relative hard look at the natural forces of change. Setting aside lands for non-use does not encourage wise use symbiotic tenets, which man has traditionally formed in his coexistence with nature.

Gold Hill, Utah
November 2003
The Gold Hill (Clifton) mining district is located 162 miles, by road, west of Salt Lake City. All but the last 12 miles of road is paved. The settlement of Gold Hill (pop. 10) lies at an elevation of 5,321 feet in desert mountains, the highest of which, Dutch Mountain, is 7,800 feet above sea level. Ponderosa pine grows at the highest elevations, with a zone of pinyons and junipers below that.

Life in the Alaska Gold Rush
July 2007
The discovery of gold in the Klondike in August 1896 brought a rush that became a bonanza for a few, and hardship and disaster for many. The remoteness of the discovery site, and the extremely harsh climate made the effort to recover gold foolhardy for all but the most prepared.
