John Seibel conquering the Sulfate Pile

Dexter No. 7 Mine, Calf Mesa Mining District, Emery County, Utah, USA

In 1988 most of the species described from the Dexter No. 7 mine could be found in a small pile of ore near the portal. The sulfates were distributed nicely by solution and evaporation into openings and on to rock surfaces in the pile. Collecting was generally easy, although some of the sulfates had cemented the rock into fairly tough masses.

Calf Mesa Mining District, Emery County, Utah, USA

Specimens collected from a large 'ore' pile at the adit to the Dexter No. 7 mine on Calf Mesa. The blue specimens suggest coloration from jordisite or ilsemannite but Mo minerals have not been reported here.

Edw. Geo. Wood, Microscope

A microscope and accessories manufactured by Edward George Wood, Optician, (1812-1896) of London. This instrument was used by my maternal grandfather while at Harvard in the 1880's. Some accompany slides are dated 1882. Hollis Webster taught languages but had a life-long interest in botany and collected minerals as well.
