9th CIRCUIT COURT OF APPEALS

Last week a federal appeals court handed down an interesting decision: that the United States Forest Service could no longer charge auto parking fees for hikers (perhaps even rock hounds)  heading to certain trails in the Catalina Mountains near Tucson, AZ.

The 9^th Circuit Court of Appeals ruling could bring an end, or at least change the outlook, on fees gathered by the USFS to pay for improvements.  I am uncertain if the ruling applies only to the Catalina Mountains or to fees the USFS collects at numerous other locations (probably the latter).  As I understand it, the USFS has collected, since 1996, parking fees for hikers in some of the canyon areas of the Catalina’s. Since the hikers were not using improved facilities (campgrounds etc.), fees could not be charged.  

The court case is Adam et. al. v USFS.  Perhaps it will be appealed by USFS?  I would assume that a USFS ruling would also apply to lands managed by BLM, and perhaps other federal agencies. 

 

This case may have wide implications for recreation and other fees assessed by federal land managers.  But again, it may not!  I look forward to hearing about future results.

COPPER RIVET MINE: COLORADO

VUG IN SANDSTONE COLLECTED AT COPPER RIVET MINE.  NOTE GEMMY CLEAR CALCITE PARTIALLY ENCRUSTED WITH GREEN MALACHITE AND BLUE AZURITE.  NOTE TINY GREEN ACICULAR CRYSTALS NEAR LOWER LEFT PART OF SPECIMEN. 

At the Tucson Electric Park/Kino Complex show I purchased an interesting specimen collected from the Copper Rivet Mine (uranium and copper) in Mesa County, Colorado, about 10 miles south of Gateway (Juanita Arch Quadrangle, 38.535ºN, 108.975ºW).  The seller indicated the specimens were collected in the early 1960's and that he had purchased a flat for resale; I immediately snapped up one!

Thus far I have not had access to an appropriate geological library to locate geological information.  However, the mine is very near the Utah-Colorado state line in an area of copper production; MinDat (www.mindat.org) noted that the Copper Rivet is located several miles north of the Cashin Mine.  The North Jeffco Gem and Mineral Club collected at the mine in a 2000 field trip that is described at peaktopeak.com/njeffco/2000/copperrivet/copper00_rep.php.  They described the hike to the dump and mine adit as 'strenuous".

The specimen, ~2.5 x 2.5 inches, has gemmy clear calcite crystals with coatings of boytrodal malachite and microcrystals of azurite appearing as "blobs".  And, there are quite tiny, green acicular crystals of what I am guessing is malachite although their green color is a different shade than the boytrodal form.  MinDat listed the following minerals known from the Copper Rivet: Azurite, Baryte, Bornite, Calcite, Chalcocite, Chalcopyrite, Luzonite, Malachite.
